x

Question

Factor the expression

7 (3 x - 2 y) (3 x + 2 y)

Evaluate

63 x^{2} - 28 y^{2}

Factor out 7 from the expression

7 (9 x^{2} - 4 y^{2})

Solution

More Steps

Evaluate

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

Rewrite the expression in exponential form

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

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

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

7 (3 x - 2 y) (3 x + 2 y)
