completely factor 4x^3+36x^2+4x+36

OpenStudy (anonymous):

I know it is going to have 4(x^3+9x^2+x+9) for the next step. Is that completely factored?

OpenStudy (luigi0210):

Nope, finish by factoring by grouping.

OpenStudy (anonymous):

x^3+x and 9x^2+9 ?

OpenStudy (luigi0210):

I think it would be better if we left that 4 back into the equation

OpenStudy (anonymous):

4(x^3+x)(9x^2+9) ?

OpenStudy (luigi0210):

Not exactly: |dw:1385963722885:dw| Make sense?
