Answer 2

$\sf \bf \huge {\boxed {\mathbb {QUESTION}}}$

$\tt Multiply\:using \:appropriate \:identity$

$\sf \bf (x+7)(x+7)$

$\sf \bf \huge {\boxed {\mathbb {ANSWER}}}$

$\sf \bf\implies (x+7)(x+7)$

$\sf \bf\implies {(x+7)}^{2}$

${\boxed {\color {green} {\sf \bf Identity ={(a+b)}^{2}={a}^{2}+2ab+{b}^{2}}}}$

$\sf \bf \implies {(x+7)}^{2}={x}^{2}+2(x)(7)+{(7)}^{2}$

$\implies{\boxed {\color {red} {{(x+7)}^{2}={x}^{2}+14x+49}}}$

$\sf \bf {(a+b)}^{2}={a}^{2}+2ab+{b}^{2}$

$\sf \bf {(a-b)}^{2}={a}^{2}-2ab+{b}^{2}$

$\sf \bf (a+b) (a-b) ={a}^{2}-{b}^{2}$
