I tired my best on this one...
Unfortunately, your work is incorrect. Based on the original problem, it looks like you multiplied things together. The parentheses don't matter in this problem. Simply combine 6y^2 and 3y^2 to make 9y^2. Because there is only one monomial with just one y, you leave +4y alone. You then combine -3 and +2 to make -1. The answer is 9y^2+4y-1.
