c^{2} - 16

$c^{2} - 16$

Step 1

Rewrite

16

$16$ as

4^{2}

$4^{2}$ .

c^{2} - 4^{2}

$c^{2} - 4^{2}$

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 = c

$a = c$ and

b = 4

$b = 4$ .

(c + 4) (c - 4)

$(c + 4) (c - 4)$

c^{2} - 16

$c^{2} - 16$
