I can't see the image

anonymous · Answer

no? well its of a rectangle with a x + 5 on the right side and a 2x - 4 on the bottom.

anonymous · Answer

an x + 5*

anonymous · Answer

so it would be (ax + 5)(2x-4)
expand

anonymous · Answer

no sorry just (x + 5) (2x - 4)

anonymous · Answer

meant to put an instead of a... sorry hehe

anonymous · Answer

Oh ok.
Then we have (x + 5) (2x - 4)
p(x) = 2x² - 4x + 10x - 20
p(x) = 2x² + 6x - 20
is that what you mean?

Its looks good to me... but would you mind explaining a little further in to how you got that answer??

anonymous · Answer

wait, nvm I understand. lol thanks for your help!! :)
