Question

(7s – 8s⁴ – 3) + (-4s – 6s⁴ – 2s²)

Answer 1

1. Simplify

7s - 8s4 - 3 - 4s - 6s4 - 2s2

2. Collect like terms

(7s - 4s) + (-8s^4 - 6s^4) - 3 - 2s^2

3. Answer/simplify

answer: 3s - 14s^4 - 3 - 2s^2

Answer 2

The simplified expression is: -14s⁴-2s²+3s-3.

First group all the like terms together.

(-8s⁴)+(-6s⁴)=-14s

-2s

7s+(-4s)=3s

-3

Then put the expression back together, starting with the term that has the largest exponent, then working your way down. You would then get: -14s⁴-2s²+3s-3.
