Question

Where do I keep messing up at?

(8p2+3p+7)–(3p+5)

8p2+6p2+5

what am I doing wrong?

Answer 1

there is a mistake in the last two terms..

Answer 2

when you multiply the - sign in the second brackets you basically put + sign instead of - sign

Answer 3

So how do I fix it?

Answer 4

3p - 3p = 0
and 7 - 5 = 2

So the final answer is 8p^2 +2

Answer 5

Thank you.

Answer 6
