first factor out -x I would suggest then try to factor the quaratic trinomial
I want see how you would do it
OpenStudy (anonymous):
how?
OpenStudy (xapproachesinfinity):
if you factor -x what do you get?
OpenStudy (kva1992):
pretty much take the lost common value from each of the common variables
OpenStudy (xapproachesinfinity):
-3x(4x^2-15x-4)

I'm just correcting the answer, it should be D. I was not paying attention and missed it
OpenStudy (anonymous):
a. -3(4x+1)(x-4)
b.-3x(2x+1)(2x-4)
c.-3x(4x+1)(x-4)
d.-3(2x+1)(2x-4)
OpenStudy (xapproachesinfinity):
Oh no im sorry, i'm correcting to you, I was with onther person with different problem lol
OpenStudy (xapproachesinfinity):
