(4w2 – 7w – 6) – (8w2 + 2w – 3) A. –4w2 – 9w – 3 B. 12w2 + 9w + 3 C. –4w2 – 5w – 9 D. 12w2 – 5w – 9

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

no

OpenStudy (anonymous):

-4w^2-5w-3

OpenStudy (anonymous):

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

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

how did you get 9w

jhonyy9 (jhonyy9):

A is right sure

OpenStudy (anonymous):

-7w - 2w = -9w

OpenStudy (anonymous):

That's how I got the -9w.

OpenStudy (anonymous):

change the minus to a plus and change the sign

OpenStudy (anonymous):

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

OpenStudy (anonymous):

ok got it. might need help soon. thank you

OpenStudy (anonymous):

np :)
