factor out the common factor

OpenStudy (anonymous):

Ok so I started to factor them out and I came up with (15x^3-5x)(5x+2) which is wrong

OpenStudy (lgbasallote):

hint: the common factor is x^2

OpenStudy (lgbasallote):

use if you notice, all of them are divisible by x^2

OpenStudy (lgbasallote):

because*

OpenStudy (anonymous):

U may factor out 5x^2

OpenStudy (anonymous):

Right I got this far and got stuck (15x^2+____)(5x^2-____)

OpenStudy (anonymous):

5x^2( ) All you need to do is fill in the bracket

OpenStudy (anonymous):

5x^2(15x^2+7x-2x) is the answer

OpenStudy (anonymous):

Close, -2 at the end, not -2x

OpenStudy (anonymous):

ok Thank you so much
