To solve this problem, the first thing we should do is eliminate the parentheses in the expression. To do this, we must understand that subtraction of a negative equals a positive, meaning that we can get rid of the second set of parentheses and change the minus a negative to a plus sign. If we do this, we get:
(-13w² + 13) + 2w²
Next, we can get rid of the parentheses around the first two terms because there is addition inside and outside of the parentheses. Since there ins no multiplication or negatives, we can simply rewrite the same expression with no parentheses.
-13w² + 13 + 2w²
Now, we must combine like terms. This means adding terms that have the same variable to the same degree. in this case, we must add -13w² and 2w². To do this, we simply add their coefficients, giving us:
-11w² + 13
Therefore, the expression directly above is your answer.
Hope this helps!
