Answer 2

$\huge \star \; \bf \underbrace {ANSWER} \: \star$

‣ Given :

$\sf {(x + 2) (x + 5)}$

‣ To Find :

$\textsf {Product}$

‣ Identity :

$\fbox {\sf {(x + a) (x + b) = x² + (a + b)x + ab}}$

‣ Solution :

$\rightarrow \sf {(x + 2) (x + 5)}$

$\sf {= x² + (2 + 5)x + (2 × 5)} \: \: \: \: \: \: \: [ \therefore \textsf {By using Identity}]$

$\sf {= x² + 7x + 10}$

$: \implies \sf {\underline {\underline {Hence, \: the \: answer \: is \: x² + 7x + 10.}}}$
