Question

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

Factor

$4\left(-2m-1\right)\left(2m-1\right)$

Solution Steps

Factor out $4$.

$$4\left(1-4m^{2}\right)$$

Consider $1-4m^{2}$. Rewrite $1-4m^{2}$ as $1^{2}-\left(2m\right)^{2}$. The difference of squares can be factored using the rule: $a^{2}-b^{2}=\left(a-b\right)\left(a+b\right)$.

$$\left(1-2m\right)\left(1+2m\right)$$

Reorder the terms.

$$\left(-2m+1\right)\left(2m+1\right)$$

Rewrite the complete factored expression.

$$4\left(-2m+1\right)\left(2m+1\right)$$

Evaluate

$4-16m^{2}$
