Question

Simply the attached question​

Answer 1

=x⁴−x³−14x²

Explanation:

Let's simplify step-by-step.

x²(3x²+5x−4)−2x²(x²+3x+5)

Distribute:

=(x²)(3x²)+(x²)(5x)+(x²)(−4)+−2x⁴+−6x³+−10x²

=3x⁴+5x³+−4x²+−2x⁴+−6x³+−10x²

Combine Like Terms:

=3x⁴+5x³+−4x²+−2x⁴+−6x³+−10x²

=(3x⁴+−2x⁴)+(5x³+−6x³)+(−4x²+−10x²)

=x⁴+−x³+−14x²

ANS-

=x⁴−x³−14x²
