Question

"Perform the subtraction and simplify.
7y2 - 3y + 4-(3y-6)

Answer 1

7y²-6y+10

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 :)
