Use the difference of squares equation: $(a^{2} - b^{2}) = (a + b) (a - b)$ $(a^2-b^2)=(a+b)(a-b)$ .

Identify $a$ $a$ and $b$ $b$ , and substitute the values into the equation.

$36 x^{2} - 49$ $36x^2-49$ is in the form of the difference of squares: $(a^{2} - b^{2}) = (a + b) (a - b)$ $(a^2-b^2)=(a+b)(a-b)$

$a = 6 x$ $a=6x$
$b = 7$ $b=7$

$36 x^{2} - 49 = (6 x + 7) (6 x + 7)$ $36x^2-49=(6x+7)(6x+7)$
