factor 16x^2-4x^2

Solution

factor

16 x^{2} - 4 x^{2}

Solution

12 x^{2}

Solution steps

16 x^{2} - 4 x^{2}

Rewrite

16 x^{2}

as

(2^{2} x)^{2}

Rewrite

4 x^{2}

as

(2 x)^{2}

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

Apply Difference of Two Squares Formula:

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

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

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

Simplify

(2^{2} x + 2 x) (2^{2} x - 2 x) : 12 x^{2}

= 12 x^{2}
