Question

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

Answer 1

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

Answer 2

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

Answer 3

use the 5x^2 and factor more

Answer 4

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

Answer 5

okay, thanks :D
