Question

Evaluate : (4x+6y)²​

Answer 1

Step-by-step explanation:

(4x)²+(6y)²+2(4x)(6y)

16x²+36y²+48xy

Answer 2

Answer:

$({a + b})^{2} = {a}^{2} + {b}^{2} + 2ab$

$Here, a = 4x \: and \: b = 6y$

$\: \: \: \: {(4x + 6y)}^{2} \\ = {(4x)}^{2} + {(6y )}^{2} + 2 \times 4x \times 6y \\ = 16 {x}^{2} + 36 {y}^{2} + 48xy$
