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
