Question

9x square +6xy+y square​

Answer 1

I think u wanna us to factorise it...

If it's so, then

Here is ur answer mate:-

9x²+6xy+y²

• to factorise this, we must apply an algebraic identity in this equation.

• As it is in a form of (x²+2xy+y²) we must apply (x+y)² identity.

→(3x)²+2(x+y)+(y)²

→(3x+y)²

hence, factorisation of 9x²+6xy+y² is (3x+y)²

Answer 2

${\huge{\green{\underline{\underline{\pink{Aηѕωєя \: :}}}}}}$

9x²+6xy+y² = (3x)² + 2(3x)(y)+(y)²

Using identity I

= (3x+y)²=(3x+y)(3x+y)
