Answer 1

Answer:

2x to the second power +x−10

Step-by-step explanation:

Let's simplify step-by-step.

5x+x2−4−(4x−x2+6)

Distribute the Negative Sign:

=5x+x2−4+−1(4x−x2+6)

=5x+x2+−4+−1(4x)+−1(−x2)+(−1)(6)

=5x+x2+−4+−4x+x2+−6

Combine Like Terms:

=5x+x2+−4+−4x+x2+−6

=(x2+x2)+(5x+−4x)+(−4+−6)

=2x2+x+−10
