What is an algebraic equation?

An algebraic equation is a mathematical statement that contains one or more variables and expresses a relationship between them using mathematical symbols and operations such as addition, subtraction, multiplication, division, and exponentiation. These equations are used to solve for the values of the variables by performing various mathematical manipulations and operations.

What is the difference between an equation and an expression?

An equation is a statement that shows the equality between two expressions, usually separated by an equal sign, while an expression is a mathematical phrase that can contain variables, constants, and operations but does not contain an equal sign. In an equation, you solve for the value of the variable that makes the two sides equal, whereas an expression is simply a mathematical statement that may or may not have a specific value.

How do you solve a linear equation with one variable?

To solve a linear equation with one variable, isolate the variable by performing the same operation to both sides of the equation to keep it balanced. This involves simplifying the equation by combining like terms and then using inverse operations like addition, subtraction, multiplication, and division to isolate the variable and find its value.

How do you solve a quadratic equation?

To solve a quadratic equation, you can use the quadratic formula which is x = (-b ± ?(b^2 - 4ac)) / 2a, where a, b, and c are the coefficients of the quadratic equation in the form ax^2 + bx + c = 0. Substitute these values into the formula and solve for x by taking into account the plus/minus sign. This will give you the two possible solutions for the quadratic equation.

What is a system of equations?

A system of equations is a set of equations that are solved simultaneously to find the values of the variables that satisfy all the equations in the system. It involves finding a common solution that satisfies all the equations in the system, typically through methods like substitution, elimination, or graphing. Systems of equations are commonly used in various fields of mathematics and science to model real-world situations and solve complex problems involving multiple variables.

How do you solve a system of equations using the substitution method?

To solve a system of equations using the substitution method, you first solve one of the equations for one variable in terms of the other. Then, you substitute this expression into the other equation and solve for the remaining variable. Finally, you back-substitute this value into one of the original equations to find the value of the first variable. This process allows you to find the unique solution to the system of equations.

How do you solve a system of equations using the elimination method?

To solve a system of equations using the elimination method, you first align the equations so that like terms are lined up. Then, you manipulate the equations by adding or subtracting them to eliminate one of the variables. Next, solve for the remaining variable. Finally, substitute the solved variable back into one of the original equations to find the value of the other variable.

What is a rational equation?

A rational equation is an equation that involves one or more rational expressions, where a rational expression is a fraction with polynomials in the numerator and denominator. When solving rational equations, the goal is usually to find the values of the variable that make the equation true while considering any restrictions on the variable that would make the denominator equal to zero.

How do you solve a rational equation?

To solve a rational equation, first factor the numerator and denominator as much as possible. Next, identify any restrictions on the variable that would make the denominator equal to zero. Then, cross multiply to eliminate the fractions and simplify the equation. Solve for the variable, making sure to check your solutions against the original equation to ensure they are valid. Remember to exclude any solutions that would make the original denominator zero.

What is a radical equation?

A radical equation is an equation that contains a variable within a radical (square root, cube root, etc.). These types of equations often involve isolating the radical expression and eliminating it by squaring both sides of the equation to solve for the variable. It is important to check for extraneous solutions when solving radical equations, as some solutions may not be valid for the original equation.
