Question

find using identities (2x+3y)²​

Answer 1

We know that (a + b)² = a² + b² + 2ab

So,

${(2x + 3y)}^{2} = {(2x)}^{2} + {(3y)}^{2} + 2 \times 2x \times 3y = 4 {x}^{2} + 9 {y}^{2} + 12xy$

Answer 2

Answer:

Identity:(a+b)²=a²+b²+2ab

By using the identity, we have:

(2x+3y)²=(2x)+(3y)+(2)×(2x)×(3y)

(2x+3y)²=2x+3y+12xy
