Question

An expression is shown below:
2x3y + 18xy - 10x2y - 90y

Part A: Rewrite the expression so that the GCF is factored completely. (3 points)

Part B: Rewrite the expression completely factored. Show the steps of your work. (4 points)

Part C: If the two middle terms were switched so that the expression became 2x3y - 10x2y + 18xy - 90y, would the factored expression no longer be equivalent to your answer in part B? Explain your reasoning. (3 points)

Answer 1

Are you asking us to help you or do the work for you?

Answer 2

I need help for part B and C. I already have A done

Answer 3

okay show ur work
what u got for part A ?

Answer 4

2x^3y + 18xy - 10x^2y - 90y= 2y(x^3-5x^2+9x-45)
for part a

Answer 5

You probably just want direct answers.

Answer 6

no, I said I need help. I forgot how to factor and I am not good at factoring either. so I would like an explanation to.

Answer 7

yep that's right
to factor parentheses you have to apply group method

Answer 8

Have you done any research or learned this in school at all? a minute, with your textbook should give you the answer.

Answer 9

so if I break it down would it look like 2y(x^3-5x^2+9x-45)
2y[x^3-5x^2 +9x-45] I know how to that then I get confused with the next step
