Answer:
=14s4−7s2+15
Step-by-step explanation:
Steps:
1: Distribute the Negative Sign
=12s4−6s2+4s+6s4−4s+27+−1(4s4+s2+12)
=12s4+−6s2+4s+6s4+−4s+27+−1(4s4)+−1s2+(−1)(12)
=12s4+−6s2+4s+6s4+−4s+27+−4s4+−s2+−12
2: Combine Like Terms
=12s4+−6s2+4s+6s4+−4s+27+−4s4+−s2+−12
=(12s4+6s4+−4s4)+(−6s2+−s2)+(4s+−4s)+(27+−12)
=14s4+−7s2+15
Answer: =14s4−7s2+15
