m^{2} - 4

$m^{2} - 4$

Step 1

Rewrite

4

$4$ as

2^{2}

$2^{2}$ .

m^{2} - 2^{2}

$m^{2} - 2^{2}$

Step 2

Since both terms are perfect squares, factor using the difference of squares formula,

a^{2} - b^{2} = (a + b) (a - b)

$a^{2} - b^{2} = (a + b) (a - b)$ where

a = m

$a = m$ and

b = 2

$b = 2$ .

(m + 2) (m - 2)

$(m + 2) (m - 2)$

m^{2} - 4

$m^{2} - 4$
