Question

How do I solve, 9z^3 + 36z^2 - 8z - 32

Answer 1

Write it like this :
\((9z^3 + 36z^2) - (8z+32)\)

\((9z^2(z + 4)) - 8(z+4) \)

Take z+4 common now...

Answer 2

How did you get the (9z^2(z+4))-8(z+4)?

Answer 3

Consider this only for now : \((9z^3 + 36z^2)\)

Take 9z^2 common from it.

Answer 4

Do you mean find the GCF of 9 & 36? I think its 4.
