Question

Simplify: (x²+2y) (x-3y) +5y²
​

Answer 1

$\huge\mathfrak\red{Answer⤵}$

$(x²+2y) (x-3y) +5y² \\ {x}^{3} - 3 {x}^{2}y + 2xy - 6 {y}^{2} + 5 {y}^{2} \\ {x}^{3} - 3 {x}^{2}y + 2xy - {y}^{2}$

Answer 2

$= ( {x}^{2} + 2y)(x - 3y) + 5 {y}^{2} \\ \\ = {x}^{2} (x - 3y) + 2y(x - 3y) + 5 {y}^{2} \\ \\ = {x}^{3} - 3 {x}^{2}y + 2xy - 6 {y}^{2} + 5 {y}^{2} \\ \\ = {x}^{3} - 3 {x}^{2}y + 2xy - {y}^{2}$
