Answer:
2w^2 -7w-2
Step-by-step explanation:
(4w^2 – 4w – 8) – (2w^2 + 3w – 6)
Distribute the minus sign
(4w^2 – 4w – 8) – 2w^2 - 3w + 6
I like to line them up vertically
4w^2 – 4w – 8
– 2w^2 - 3w + 6

2w^2 -7w-2
Answer:
2w^2 - 7w - 2.
Step-by-step explanation:
We can remove the first set of parentheses without changing the content but we need to multiply the contents of the second one by -1:
(4w^2 – 4w – 8) – (2w^2 + 3w – 6)
= 4w^2 – 4w – 8 - 2w^2 - 3w + 6
= 2w^2 - 7w - 2.
