Answer:
The answer is D
Step-by-step explanation:
Let's simplify step-by-step.
3x2−3+9x3−(4x3−2x2+16)
Distribute the Negative Sign:
=3x2−3+9x3+−1(4x3−2x2+16)
=3x2+−3+9x3+−1(4x3)+−1(−2x2)+(−1)(16)
=3x2+−3+9x3+−4x3+2x2+−16
Combine Like Terms:
=3x2+−3+9x3+−4x3+2x2+−16
=(9x3+−4x3)+(3x2+2x2)+(−3+−16)
=5x3+5x2+−19
Answer:
=5x3+5x2−19
