Factor x^2-225y^2

$x^{2} - 225 y^{2}$

Step 1

Rewrite $225 y^{2}$ as ${(15 y)}^{2}$ .

$x^{2} - {(15 y)}^{2}$

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 $b = 15 y$ .

$(x + 15 y) (x - (15 y))$

Step 3

Multiply $15$ by $- 1$ .

$(x + 15 y) (x - 15 y)$

Factor x^2-225y^2
