Answer
2$y^{3}$ + 3$y^{2}$+ 8y -12
Work Step by Step
(2$y^{3}$+3y + 10) + (3$y^{2}$+5y - 22)
The like terms are 2$y^{3}$ , 3$y^{2}$ , 3y and 5y (both containing y) and the constant terms 10 and -22.
We begin by grouping these pairs of like terms.
= 2$y^{3}$ + 3$y^{2}$ +(3y+5y)+(10-22)
= 2$y^{3}$ + 3$y^{2}$+ 8y -12
