If you would like to solve <span>(5x^3 + 4x^2) - (6x^2 - 2x - 9), you can do this using the following steps:

</span>(5x^3 + 4x^2) - (6x^2 - 2x - 9) = <span>5x^3 + 4x^2 - 6x^2 + 2x + 9 = 5x^3 - 2x^2 + 2x + 9
</span>
The correct result would be <span>D. 5x^3 – 2x^2 + 2x + 9.</span>

Divide by 15 on each side

15x/15 =180/15
