factor 4m^2-16m^2

Solution

factor

4 m^{2} - 16 m^{2}

Solution

- 12 m^{2}

Solution steps

4 m^{2} - 16 m^{2}

Rewrite

4 m^{2}

as

(2 m)^{2}

Rewrite

16 m^{2}

as

(2^{2} m)^{2}

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

Apply Difference of Two Squares Formula:

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

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

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

Simplify

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

= - 12 m^{2}
