Here we consider a = (√2x+√3y) and b= (√2x-√3y).

Using formula

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

(√2x + √3y)² + 2(√2x+ √3y)(√2x - √3y)+(√2x-√3y)²

={(√2x+√3y)+(√2x-√3y)}²

={2√2x}²

=4 x 2x²

=8x²

rajeshpunamkumari84: 8x² is the right answer.

rajeshpunamkumari84: plz follow me

ayushkumar04: thank you

ayushkumar04: but can you say how 2√2x^2 came

rajeshpunamkumari84: (2√2x)² = 2²X(√2x)²= 4X2x = 8x
