Blue Highlighted Text denotes exercises that are similar to question items found on the GED. In general, difficulty increases as you go down the list of exercises. You are encouraged to master the exercises at the top and work your way down.

Add and Subtract Polynomials

Add, subtract, multiply, divide, and factor polynomials [Example: (x + 8) (x + 4); factor 3x2 + 10x - 8]

Multiply and Factor Polynomials

Add, subtract, multiply, divide, and factor polynomials [Example: (x + 8) (x + 4); factor 3x2 + 10x - 8]

Create polynomials to represent problem situations or word-to-symbol translations

[Example: a triangle has three sides with the following lengths: 2x + 1 units, 3x + 5 units, and 4x - 1 units. Write an algebraic expression for the perimeter of the triangle in units.]
