Simplify the 2 after the x is square

Answer 1

5x2−3x−3

Explanation:

Let's simplify step-by-step.

x2+2x+3−(−4x2+5x+6)

Distribute the Negative Sign:

=x2+2x+3+−1(−4x2+5x+6)

=x2+2x+3+−1(−4x2)+−1(5x)+(−1)(6)

=x2+2x+3+4x2+−5x+−6

Combine Like Terms:

=x2+2x+3+4x2+−5x+−6

=(x2+4x2)+(2x+−5x)+(3+−6)

=5x2+−3x+−3
