Step-by-step explanation:

Reduce = Deduct = Subtract

7y + 2y^2 - 7 - (3 - 4y)

distribute the negative sign outside 3-4y.

7y+2y^2-7 - 3 + 4y

collect like terms, meaning try to make similar components of the equation together at one place.

7y & 4y are like terms in this case.

7y + 4y + 2y^2 - 7 - 3

11y + 2y^2 - 10

rewrite 2y^2 infront of the equation because it has the highest degree which is 2.

2y^2 + 11y - 10
