Question

What is the difference of the polynomials?

Answer 1

Answer:

D

Step-by-step explanation:

We want to find the difference between the two polynomials:

$(5x^3+4x^2)-(6x^2-2x-9)$

Distribute the negative:

$=(5x^3+4x^2)+(-6x^2+2x+9)$

Rearrange the terms:

$=(5x^3)+(4x^2-6x^2)+(2x)+(9)$

Combine like terms. Hence:

$=5x^3-2x^2+2x+9$

Our answer is D.
