factor x^2-9y^2

Solution

factor

x^{2} - 9 y^{2}

Solution

(x + 3 y) (x - 3 y)

Solution steps

x^{2} - 9 y^{2}

Simplify

9 y^{2} : (3 y)^{2}

= x^{2} - (3 y)^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

x^{2} - (3 y)^{2} = (x + 3 y) (x - 3 y)

= (x + 3 y) (x - 3 y)
