Type your math problem... 9xy-4a^2xy

x

Question

Factor the expression

x y (3 - 2 a) (3 + 2 a)

Evaluate

9 x y - 4 a^{2} x y

Factor out x y from the expression

x y (9 - 4 a^{2})

Solution

More Steps

Evaluate

9 - 4 a^{2}

Rewrite the expression in exponential form

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

Use a^{2} - b^{2} = (a - b) (a + b) to factor the expression

(3 - 2 a) (3 + 2 a)

x y (3 - 2 a) (3 + 2 a)
