Answer 7

when you multiply 4x times 2x^2 you get
\[ 4 \cdot x \cdot 2 \cdot x^2 = 4\cdot 2 \cdot x\cdot x^2 = 8 x^3 \]

can you redo it ?

Answer 8

Yeah, is that the only thing I did wrong?

Answer 9

most of it seems off... but I can't tell where you went wrong. so do it step by step

Answer 10

you will have 6 multiply problems that you have to do... before simplifying..

Answer 11

the first 3 multiply problems are 4x times each of the terms
then 3 more: -3 times each of the terms
