Factor 16x^2-169y^2

$16 x^{2} - 169 y^{2}$

Step 1

Rewrite $16 x^{2}$ as ${(4 x)}^{2}$ .

${(4 x)}^{2} - 169 y^{2}$

Step 2

Rewrite $169 y^{2}$ as ${(13 y)}^{2}$ .

${(4 x)}^{2} - {(13 y)}^{2}$

Step 3

Since both terms are perfect squares, factor using the difference of squares formula, $a^{2} - b^{2} = (a + b) (a - b)$ where $a = 4 x$ and $b = 13 y$ .

$(4 x + 13 y) (4 x - (13 y))$

Step 4

Multiply $13$ by $- 1$ .

$(4 x + 13 y) (4 x - 13 y)$

Factor 16x^2-169y^2
