However, x and x 2 are not like terms because each term has x raised to a different power. Like terms are variables that have the same letter and same exponent. These terms are having different coefficients but the same variable. For example, x 2 and 2x 2 are like terms. We notice that each term has an a a in it and so we "factor" it out using the distributive law in reverse as follows, ab +ac = a(b+c) a b + a c = a ( b + c) Let's take a look at some examples. Simplify and solve for x=2 and y=5. Quadratic functions aren't much different. The terms 3 x and 3x 2 are not like terms because the indices are different.
