Question

An expression is shown below:

2x3 + 10x2 − 4x2y − 20xy

Part A: Rewrite the expression by factoring out the greatest common factor. (4 points)

Part B: Factor the entire expression completely. Show the steps of your work. (6 points)

Answer 1

2x3 + 10x2 − 4x2y − 20xy

Explanation:

1. Greatest common Factor= 52

2 x 3 + 10 x 2 - 4 x 2y - 20 x y

2 x 3 + 10 x 2 - 4 x 20 - 2y x y

6 + 20 - 80 - 2

26 - 78

52.

2.Example: factor 2y+6

Both 2y and 6 have a common factor of 2: 2y is 2 × y. 6 is 2 × 3.
