Factor x^2-121y^2

$x^{2} - 121 y^{2}$

Step 1

Rewrite $121 y^{2}$ as ${(11 y)}^{2}$ .

$x^{2} - {(11 y)}^{2}$

Step 2

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

$(x + 11 y) (x - (11 y))$

Step 3

Multiply $11$ by $- 1$ .

$(x + 11 y) (x - 11 y)$

Factor x^2-121y^2
