26 different types of equations (2023)

26 different types of equations (1)

Although not obvious, learning equations is important in our daily life. Without them we wouldn't have the computers, GPS, satellite television and other inventions that make modern society what it is.

SomeEquations that changed the way we liveThey are the Pythagorean Theorem, the Fundamental Theorem of Analysis, and Newton's Universal Law of Gravitation, to name a few.

The equation is important for medicine, business, computer science, engineering and more. Read on for more information on this dynamic concept.

Types of Equations - Algebraic

cubic equation

A cubic equation is a polynomial equation in which the largest sum of the exponents of the variables in each term is three. In other words, it's an equation.with a cubic polynomial; that is, one of the forms. It has the following form:

Machado3+ bx2+ cx + d = 0 for a ≠ 0

exponential equation

26 different types of equations (2)

Exponential equations have variables instead of exponents and can be solved using this property: axax = ayay => x = y. Examples for this are:

  • 4X= 0
  • 8X= 32
  • andb= 0 (where "a" is the base and "b" is the exponent)

Irrational polynomial equation

Irrational polynomial equations are those equations with at least one polynomial under the root sign.

linear equation

26 different types of equations (3)

Linear equations are those in which each term is a constant or the product of a single variable and a constant. When there are two variables, the graph of the linear equation is always a straight line. A linear equation typically looks like this:

y = mx + c, Metro ≠≠ 0

In this example, m is known as the slope and c represents the point where it intersects the y-axis.

In linear equations with different variables:

Single Variable Equation: An equation that has only one variable. Examples for this are:

  • 8a – 8 = 0
  • 9a = 72

The equation has two variables: An equation that has only two types of variables. Examples for this are:

  • 9a + 6b – 82 = 0
  • 7x + 7a = 12
  • 8a - 8d = 74

The three variable equation: This is an equation with only three types of variables in the equation. Examples for this are:

  • 13a - 8b + 31c = 74
  • 5x + 7a - 6z = 12
  • 6p + 14q – 74 + 82 = 0

logarithmic equation

These are equations where the unknown is always affected by a logarithm.

polynomial equation

26 different types of equations (4)

Contain polynomial equationsVariables or indeterminate and coefficients. They are involved in operations such as addition, subtraction, multiplication, and non-negative integer exponents. Examples for this are:

  • ax + by + c = 0 ax + by + c = 0 with degree = 1 and two variables
  • Machado2+ bx + c = 0ax2+ bx = c = 0 with degree = 2 and one variable
  • ax + b = 0 with degree = 1 and one variable
  • axy + c = 0axy + c = 0 with degree = 2 and two variables

26 different types of equations (5)

A quadratic equation is aA second class equationwhere a variable contains the variable that has an exponent of two. Below is an example and the general form.

Machado2+ bx + c = 0, a ≠≠ 0

Other examples are:

  • 5a2- 5a = 35
  • 8x2+ 7x – 75 = 0
  • 4 years2+ 14 years – 8 = 0

quadratic equation

Quadratic equations are quadratic equations and an equation that equates to zero a quadratic polynomial in this form:

f(x) = ax4+ bx3+ CX2+ dx + e = 0 und a ≠ 0

The derivative of a quadratic function is a cubic function.

quintic equation

A quintic equation is a polynomial equation where five is the highest power of the variable. The formula used is:

ax^5 + bx^4 + cx^3 + dx^2 + ex + f = 0

Examples for this are:

  • x^5 + x^3 + x
  • y^5 + y^4 + y^3 + y^2 + y + 1

radical equation

Radical equations are those that have a maximum exponent in the variable that is 12 and that have more than one term. A radical equation can also be said to be one in which the variable is enclosed in a radical symbol, usually in the form of a square root. Examples for this are:

  • + 10 = 26
  • +x – 1

rational equation

A rational equation implies rational expressions.

transcendent equations

Transcendent equations are equations thatcontain transcendent functions. Exponential equations are examples of transcendental equations.

types of chemical reactions

chemical combination reactions

In this reaction, two or more reactants form a product.

Also, more than one product can be formed in a combined chemical reaction, depending on the conditions or the relative amounts of the reactants.

combustion chemical reactions

26 different types of equations (9)

Chemical combustion reactions take place when a compound, usually containing carbon, combines with gaseous oxygen from the air. This process is called combustion because heat is the most important product in most chemical combustion reactions.

Propane is part of the compounds called hydrocarbons, which are compounds made up of only carbon and hydrogen. Heat is the result of this reaction. In addition, combustion chemical reactions are also a type of chemical redox reaction.

chemical decomposition reactions

In reality, chemical decomposition reactions are the exact opposite of combination reactions. In decomposition reactions, a single compound breaks down into two or more substances of a simpler nature, mostly compounds and/or elements.

Double displacement chemical reactions

Single displacement reactions involve the displacement of a single chemical species; However, in double displacement reactions, also called metathesis reactions, two species are displaced, usually ions.

Very often such chemical reactions take place in a solution, forming water (neutralization reactions) or an insoluble solid (precipitation reactions).

Chemical neutralization reactions

This is another type of chemical double displacement reaction that occurs between a base and an acid. This type of chemical double displacement reaction is called a neutralization reaction and it forms water. Examples for this are:

The mixture of sodium hydroxide (lye) and sulfuric acid (car battery acid) is a reaction that shows up as follows:

Chemical polymerization reactions

Polymerization is a process in which monomer molecules react with each other in a chemical reaction, resulting in the formation of polymer chains, also known as three-dimensional networks. There are numerous forms of polymerization, as well as different systems that categorize each of them. Examples for this are:

N.H.2C=CH2→ [-CH2CH2-]Norte

This equation represents the union of thousands of ethylene molecules resulting in polyethylene.

In both cellulose and starch, glucose molecules are joined with the simultaneous removal of one water molecule for each bond formed. An example of this is demonstrated as follows:

North Carolina6H12Ö6→ -[-C6H10Ö5-]-n + n2Ö

Precipitation chemical reactions

Mixing a silver nitrate solution with a potassium chloride solution gives an insoluble white. When an insoluble solid forms in solution, it is called a precipitate, and the insoluble white solid that forms is called silver chloride.

Redox chemical reactions

These reactions are also known as chemical oxidation-reduction reactions and involve the exchange of electrons.

These are also examples of other types of reactions, including combined, individual exchange, and combustion reactions, but they are all redox reactions. All involve the transfer of electrons from one chemical species to another.

Redox chemical reactions are also involved in oxidation, photosynthesis, combustion, batteries, respiration, and more.

chemical reactions with one turn

Simple displacement reactions occur when a more active element displaces or displaces a less active element from a compound. An example would be if you put some metallic zinc in a copper sulfate solution, the zinc will actually displace the copper.

In this equation, the notation (aq) means that the compound dissolves in water, which is an aqueous solution. Since zinc replaces copper in this case, it is considered more active. If you put a piece of copper in a zinc sulfate solution, nothing happens.
