Question

Simplify (6x^2 - 3 - 5x^3) - (4x^3 + 2x^2 - 8)

Answer 1

First thing's first

Let's simplify step-by-step.
6x2−3−5x3−(4x3+2x2−8)
Distribute the Negative Sign:
=6x2−3−5x3+−1(4x3+2x2−8)
=6x2+−3+−5x3+−1(4x3)+−1(2x2)+(−1)(−8)
=6x2+−3+−5x3+−4x3+−2x2+8
Combine Like Terms:
=6x2+−3+−5x3+−4x3+−2x2+8
=(−5x3+−4x3)+(6x2+−2x2)+(−3+8)
=−9x3+4x2+5
Answer:
=−9x3+4x2+5
