Answer 1

Answer:

Please check your question .

It's incorrect

Answer 2

The correct question will be :

Factorise the given polynomial

$9 {x}^{2} - 12xy + 4 {y}^{2}$

On factorising :

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

[$As \: we \: know \: that = {(a - b)}^{2} = {a}^{2} - 2ab + {b}^{2}$]
