Answer 7

oh and is that supposed to be \[-18x ^{2}\] or \[-18^{2}\] ?

Answer 8

\[2x(x^3+3x^2-9x-27)\]

Answer 9

now can he factor by grouping the inside?

Answer 10

^ yes if it is -18x^2 but if it is as he wrote -18^2 it's a different answer.

Answer 11

don't know if that was a typo or not...

Answer 12

\[2x(x^2(x+3)-9(x+3))\]

\[2x(x^2-9)(x+3)\]

difference of squares:\[2x(x+3)(x-3)(x+3)\]
