Answer:


{4x}^(2) + 12y + {9y}^(2)

Explanation:


(2x + 3y) {}^(2) \\ {(a + b)}^(2) = {a}^(2) + 2ab + {b}^(2) \\ = {(2x)}^(2) + 2 * 2x * 3y + {(3y)}^(2) \\ = 4 {x}^(2) + 12y + 9 {y}^(2) \\ hope \: it \: helps

Answer:

4x² + 12xy + 9y²

Explanation:

Assuming you require the expansion

(2x + 3y)²

= (2x + 3y)(2x + 3y)

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

2x(2x + 3y) + 3y(2x + 3y) ← distribute both parenthesis

= 4x² + 6xy + 6xy + 9y² ← collect like terms

= 4x² + 12xy + 9y²
