Question

Please include all steps to solve.... (remember the x's are variables)

(3 – 6x5 – 8x4 ) − (−6x4 – 3x – 8x5)

Answer 1

Distribute minus to -6x^4, -3x, and -8x^5
- is the same as -1

-1(-6x^4) = 6x^4
-1(-3x) = 3x
-1(-8x^5) = 8x^5

3 - 6x^5 - 8x^4 + 6x^4 + 3x + 8x^5

Combine like terms

-6x^5 + 8x^5 + 6x^4 - 8x^4 + 3x + 3

2x^5 - 2x^4 + 3x + 3 is your answer
