Question

(4w2 – 7w – 6) – (8w2 + 2w – 3)
A. –4w2 – 9w – 3

B. 12w2 + 9w + 3

C. –4w2 – 5w – 9

D. 12w2 – 5w – 9

Answer 1

is this how I start it out? (4w^2-8w^2)-(7w-2w)-(6-3)

Answer 2

\[(4w^{2} - 7w - 6) - (8w^{2} + 2w - 3) = 4w^{2} - 7w - 6 - 8w^{2} - 2w + 3\]Are you with me so far?

Answer 3

no

Answer 4

-4w^2-5w-3

Answer 5

Okay. Do you realize when it says \(-(8w^{2} + 2w - 3)\), it means \(-1(8w^{2} + 2w - 3)\)?

Answer 6

yes

Answer 7

is this right? -4w^2-5w-3

Answer 8

For the final answer, not quite. It would be \(-4w^{2} - 9w - 3\)

Answer 9

how did you get 9w

Answer 10

A is right sure

Answer 11

-7w - 2w = -9w

Answer 12

That's how I got the -9w.

Answer 13

change the minus to a plus and change the sign

Answer 14

Yeah. -7w + -2w = -9w.
