(y+6) (y+13) find the productstep by step explanation pls​

Answer:(y + 6)(y + 13) = y² + 19y + 78Step-by-step explanation:[tex] \rm \implies (y + 6)(y + 13) \\ \\ \rm \implies y(y + 13) + 6(y + 13) \\ \\ \rm \implies {y}^{2} + 13y + 6y + 78 \\ \\ \rm \implies {y}^{2} + 19y + 78[/tex]

(y+6) (y+13)Multiply 1st y by 2nd y = y^2Multiply 1st y by +13 = +13yMultiply +6 by 2nd y = +6yMultiply +6 by +13 = +78[y^2 + 13y + 6y + (6x13)]y^2 + 19y + 78:. (y+6) (y+13) = y^2 + 19y + 78
