    Solving polynomials is a fundamental part of algebra. The most basic method for solving polynomial equations is the substitution method. To solve the first-degree equation using this method, multiply both sides by the coefficient of one of the variables to isolate that variable on one side of the equation. Then substitute this value into the other ...

    A system of linear equations is a set of two or more equations written in the same format. Systems of linear equations are sets of linear equations that can be solved as a group using the same methods described below. Solving systems of linear equations means finding values for all variables in an equation so that each equation in the system is tru...

    The Laws of Exponents are rules for raising a base to an exponent. These laws can simplify exponents, multiply, divide, and negate them. Let’s take a look at each law individually Law of Multiplication: If you multiply two numbers having the same base, the product will have that base raised to the power of both factors. For example, 5(5) = 52 = 25....

    Factoring a polynomial is a fundamental concept in algebra. It can be done in several different ways. The first step is to look at the coefficients of the polynomial and determine the greatest common factor (GCF). Once you find the GCF, you should then use this to find any other factors that may be present in the polynomial. There is more than one ...

    A radical expression is a number, variable, or product raised to a power. For example, \(x^2\) is the square of x, \(x^3\) is the cube of x, and so on. A radical expression can be positive or negative depending on the value of x. The radicand (the number under the radical sign) must not contain any fractions or exponents. The base (the number writt...
