Factoring, check answer? [MEDAL. Thankyou very much! :D]

OpenStudy (anonymous):

\[5x ^{4}-15x ^{3}-50x ^{2}\] My answer was, \[5x(x ^{3}-3x ^{2}-10x)\]

OpenStudy (anonymous):

>_> So.. Not sure whether I should do \[5x ^{2}\] instead of 5x :/

OpenStudy (anonymous):

use the 5x^2 and factor more

OpenStudy (anonymous):

\[5x ^{2}(x ^{2}-3x-10) = 5x ^{2}(x-5)(x+2)\]

OpenStudy (anonymous):

okay, thanks :D
