Answer 1

Let's simplify step-by-step.

(9x2−x+15)(x2x+1)−(2x2+3x−7)(x2+x+2)

Distribute:

=(9x2)(x2x)+(9x2)(1)+(−x)(x2x)+(−x)(1)+(15)(x2x)+(15)(1)+−2x4+−5x3+x+14

=9x5+9x2+−x4+−x+15x3+15+−2x4+−5x3+x+14

Combine Like Terms:

=9x5+9x2+−x4+−x+15x3+15+−2x4+−5x3+x+14

=(9x5)+(−x4+−2x4)+(15x3+−5x3)+(9x2)+(−x+x)+(15+14)

=9x5+−3x4+10x3+9x2+29
