Factor 64w^2-121

$64 w^{2} - 121$

Step 1

Rewrite $64 w^{2}$ as ${(8 w)}^{2}$ .

${(8 w)}^{2} - 121$

Step 2

Rewrite $121$ as $11^{2}$ .

${(8 w)}^{2} - 11^{2}$

Step 3

Since both terms are perfect squares, factor using the difference of squares formula, $a^{2} - b^{2} = (a + b) (a - b)$ where $a = 8 w$ and $b = 11$ .

$(8 w + 11) (8 w - 11)$

Factor 64w^2-121
