factor a^2-9b^2

Solution

factor

a^{2} - 9 b^{2}

Solution

(a + 3 b) (a - 3 b)

Solution steps

a^{2} - 9 b^{2}

Simplify

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

= a^{2} - (3 b)^{2}

Apply Difference of Two Squares Formula:

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

a^{2} - (3 b)^{2} = (a + 3 b) (a - 3 b)

= (a + 3 b) (a - 3 b)
