factor 9x^2-4x^2

Solution

factor

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

Solution

5 x^{2}

Solution steps

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

Rewrite

9 x^{2}

as

(3 x)^{2}

Rewrite

4 x^{2}

as

(2 x)^{2}

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

Apply Difference of Two Squares Formula:

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

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

= (3 x + 2 x) (3 x - 2 x)

Simplify

(3 x + 2 x) (3 x - 2 x) : 5 x^{2}

= 5 x^{2}
