Answer

-2$y^{3}$+4$y^{2}$ +13y +13

Work Step by Step

(4$y^{2}$+8y+ 11) + (-2$y^{3}$ + 5y +2) The like terms are 4$y^{2}$ , -2$y^{3}$ , 8y and 5y (both containing y) and the constant terms 11 and 2. We begin by grouping these pairs of like terms. =4$y^{2}$ -2$y^{3}$ +( 8y + 5y) +(11+2) = -2$y^{3}$+4$y^{2}$ +13y +13
