pratik40 $hi$
$here's \: your \: answer$
$9 ({x + y})^{2} - {x}^{2}$

We know that,

$( {x + y)}^{2} = {x}^{2} + 2xy + {y}^{2}$
$so....$

$9( {x}^{2} + 2xy + {y}^{2} ) - {x}^{2}$

$9 {x}^{2} + 18xy + 9 {y}^{2} - {x}^{2}$

$8x ^{2} + 18xy + 9 {y}^{2}$

$8x^{2}+12xy + 6xy +9{y}^{2}$

=4x(2x + 3y) + 3y(2x + 3y)

=(2x + 3y)(4x + 3y)
__________________________
Final Answer :
The factorized result of the question is
(2x + 3y)(4x + 3y)

$hope \: this \: helps....$
