Answer 2

SOLUTION

TO EVALUATE

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

EVALUATION

Here the given expression is

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

We simplify it as below

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

$\sf = (a + b)(a + b)$

$\sf = a(a + b) + b(a + b)$

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

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

FINAL ANSWER

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