find each difference. (-6s² + 12s - 8) - (3s² + 8s - 6) = -9s² + 4s - 14 -9s² + 4s - 2 -9s² + 20s - 14 -9s²…

Explanation:

Step1: Distribute the negative sign

$(-6s^{2}+12s - 8)- (3s^{2}+8s - 6)=-6s^{2}+12s - 8-3s^{2}-8s + 6$

Step2: Combine like - terms for $s^{2}$ terms

$-6s^{2}-3s^{2}=(-6 - 3)s^{2}=-9s^{2}$

Step3: Combine like - terms for $s$ terms

$12s-8s=(12 - 8)s = 4s$

Step4: Combine constant terms

$-8 + 6=-2$

Step5: Write the final polynomial

$-9s^{2}+4s - 2$

Answer:

$-9s^{2}+4s - 2$
