Hey thank you so much bio_man Smiling Face with Open Mouth so my answer would be considered incorrect if I didn't write in factored form?
For 10) I meant to multiply to the -3x^2, that was a mistake! oops

Not incorrect, but I'd ask your teacher to make sure you obey his/her style. Teachers can be really subjective sometimes...

Actually, I'm not a big fan of my #10 -- it's not wrong, but can be improved. Here's how...

y=15(6x3x2)5(2+3x2x3)4

I'd take it a step further by common factoring out the numerator:

y=15(3x)(2x)5(2+3x2x3)4

Simplify:

y=3x5(2x)5(2+3x2x3)4

Simplify some more:

y=3x(2x)55(2+3x2x3)4
