c^{2} - 1

$c^{2} - 1$

Step 1

Rewrite

1

$1$ as

1^{2}

$1^{2}$ .

c^{2} - 1^{2}

$c^{2} - 1^{2}$

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 = 1

$b = 1$ .

(c + 1) (c - 1)

$(c + 1) (c - 1)$
