An expression is shown below:

3x3y + 12xy - 9x2y - 36y

Part A: Rewrite the expression so that the GCF is factored completely. Show the steps of your work. (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 3x3y - 9x2y + 12xy - 36y, would the factored expression no longer be equivalent to your answer in part B? Explain your reasoning. (3 points)

Can you combine like terms first or are you instructed to take the GCF of the terms as they are written?

i dont no how to do that

jhonyy9 · Answer

regroup them like 

(3x^3y -9x^2y) +(12xy -36y) = 3x^2y(x -3) +12y(x -3) = 

hope you can continue it ...

i cant

so factoriz out (x-3) and what will get after this ?
