Chapter 7 Unit TEST: Polynomial Equations and Factoring Answers

The table represents the multiplication of two binomials.

The formula for the area of a parallelogram is A = bh, where b is the base and h is the height.

Tomas learned that the product of the polynomials (a + b)(a2 – ab + b2) was a special pattern that would result in a sum of cubes, a3 + b3. His teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if a = 2x and b = y.

Factor –7x3 + 21x2 + 3x – 9 by grouping. What is the resulting expression?

What is the sum of the polynomials?(7x3 – 4x2) + (2x3 – 4x2)
