$a^{2} - 36$ $a^2 - 36$ can be written as $a^{2} - 6^{2}$ $a^2 - 6^2$

this is of the form:

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

so ,
$a^{2} - 6^{2} = (a + 6) (a - 6)$ $a^2 - 6^2= (a +6) (a - 6)$

the factorized form of $a^{2} - 36$ $a^2 - 36$ is:

$(a + 6) (a - 6)$ $(a +6) (a - 6)$
