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
