Question

factorise using appropriate identities : 9x²+6xy+y²​

Answer 1

Answer:

Given Equation:-

9x^2+6xy+y^2

= (3x)^2+2×3x×y+(y)^2

a^2+2ab+b^2=(a+b)^2

a=3x, b=y

by this we get,

= (3x+y)^2

Step-by-step explanation:

Answer 2

Step-by-step explanation:

$\huge \bold \red{★Answer★}$

$→9 {x}^{2} +6xy+ {y}^{2} \: \\ ({a+b})^{2} = {a}^{2}+2ab+ {b}^{2} \\ \\ = ({3x})^{2} +2(3x)y+ ({y})^{2} \\ = ({3x+y})^{2} \\ =(3x+y)(3x+y)$
