Question

factorise the following question with appropriate identity
$121 + 22x + x \sqrt{2}$
​

Answer 1

Answer:

$\red { 121 + 22x + x^{2}}\green {= (11+x)(11+x)}$

Step-by-step explanation:

121 + 22x + x²

= (11)² + 2×11×x + x²

= ( 11 + x )²

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

= ( 11 + x )( 11 + x )

Therefore.,

$\red { 121 + 22x + x^{2}}\green {= (11+x)(11+x)}$
