Question

what is (a+b)^2............

Answer 1

The answer is...

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

Answer 2

Here is your answer

$\rule{120}{2}$



$(a + b)^{2}$

=> (a + b) (a + b)

=> a(a +b) + b(a + b)

=> $a^{2}$ + ab + ab + $b^{2}$

=> $a^{2}$ + 2ab + $b^{2}$



∴ $(a + b)^{2}$ =  $a^{2}$ + 2ab + $b^{2}$
