Answer:
7y²-6y+10
Step-by-step explanation:
Be careful not to distribute the '2' throughout the parenthesis. Instead, distribute the '-' (negative). Doing this, you change the sign of the values on the inside of the parenthesis. You should get 7y²-3y+4-3y+6. From here, combine like-terms. You should be left with 7y²-6y+10 as your answer. Hope this helps :)
