What is the difference of the polynomials?

(5x3 + 4x2) – (6x2 – 2x – 9)

The difference of the polynomials (5x3 + 4x2) – (6x2 – 2x – 9) is 5x3 – 2x2 + 2x + 9.

Step-by-step explanation:

5x3−2x2+2x+9

Step-by-step explanation:

Distribute the Negative Sign:

=5x3+4x2+−1(6x2−2x−9)

=5x3+4x2+−1(6x2)+−1(−2x)+(−1)(−9)

=5x3+4x2+−6x2+2x+9

Combine Like Terms:

=5x3+4x2+−6x2+2x+9

=(5x3)+(4x2+−6x2)+(2x)+(9)

=5x3+−2x2+2x+9

step-by-step explanation:
