Question

I need help please :)

Answer 1

\[(8x ^{2}+5)-(3x ^{2}-x+7)\])

Answer 2

First you should remove the parentheses. These means distributing the negative from the subtraction sign across the 2nd set.

So:

8x^2 + 5 - 3x^2 + x - 7.

Then you combine like terms:

5x^2 - 2 + x

Then you rewrite in standard form:

5x^2 + x - 2

Answer 3

thank you :)
