Question

an expression is shown below:

2x3y + 18xy − 10x2y − 90y

Part A: Rewrite the expression so that the GCF is factored completely. (4 points)

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

Answer 1

for part A I put 2y( x^3 + 9x - 5x^2 - 45)

Answer 2

Is this what you mean? Is this what the original expression suppose to look like?

\( 2x^3y + 18xy − 10x^2y − 90y \) ?

Answer 3

yeah sorry

Answer 4

Yes part A is correct.

Answer 5

2y [ x ( x + 9) - 5(x^2+9) ]
2y (x - 5) (x^2+9)

is part b correct?

Answer 6

Yes

Answer 7

thank you
