Question

Expand using identity: (2x + 3y) 2

Answer 1

a²+2ab+b²

2x²+2*2x*3y+3y² ans

Answer 2

${\huge{\boxed{\tt{\red{Answer}}}}}$

We know ,

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

so, here

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