Question

Find the product of (x+2y)^2

Answer 1

x² + 4xy + 4y²

Explanation:

(x + 2y)²

= (x + 2y)(x + 2y)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x + 2y) + 2y(x + 2y) ← distribute parenthesis

= x² + 2xy + 2xy + 4y² ← collect like terms

= x² + 4xy + 4y²

Answer 2

x^2 + 4xy + 4y^2
