(2x − 6)(3x2 − 3x − 6).
you sure thts rite?

anonymous · Answer

$$(2x-6)(3x^2-3x-6)$$

ash2326 · Answer

@unheard did you try?

anonymous · Answer

6x3 + 24x2 − 6x + 36

no steps?

anonymous · Answer

No, I didn't try, because I forgot the method for this one.

@bzbnme Please explain how you got this,

anonymous · Answer

ok...actual i screwed it up... the first term is the same in all cases....the last term must be positive so rule out the second and fourth answers...so the only difference in the first and third one is the second and third terms... x^2 terms are all negative so the real answer should be 6x3 − 24x2 + 6x + 36... sorry for the earlier error!

anonymous · Answer

or just work it out like this $$2x(3x^2-3x-6)-6(3x^2-3x-6)$$

anonymous · Answer

you have to do two things first.|dw:1370365425708:dw| what do you get? :)
