(-7w^2=2w-1)-(-5w^2+3w-2)

12w^2+5w+1
-2w^2-5w-1
-2w^2-5w+1
-12w^2-5w-3

-2w^2-5w-1

thats wrong

I apologize for my mistake. Let's try to solve it step by step:

(-7w^2=2w-1) - (-5w^2+3w-2)

= -7w^2 - 2w + 1 + 5w^2 - 3w + 2 (distributing the negative sign)

= -2w^2 - 5w + 3

Therefore, the answer is -2w^2 - 5w + 3.
