Question

Remove brackets and then simplify:
3x(x^2 - 7x + 3) - (1 - 2x - 5x^2)

Answer 1

So here I would simply distribute, and add like terms?

Answer 2

Yes. For the second parenthesis, the minus sign is like having a -1.

Answer 3

So what's inside just changes sign and you can remove it.
3x^3-21x^2+9x-1+2x+5x^2

Answer 4

Kk. so 3x^3 - 16x^2 + 14x - 1 is our final answer. Correct?

Answer 5

The 14x I'm not on board with. All we have is 9x and 2x so 11x would be it, not 14

Answer 6

I GOT YOU ! I added the wrong terms. Alright, thanks homegirl.
