Basic Math Examples

$\frac{3 - a}{a - 3}$

Step 1

Rewrite $3$ as $- 1 (- 3)$ .

$\frac{- 1 (- 3) - a}{a - 3}$

Step 2

Factor $- 1$ out of $- a$ .

$\frac{- 1 (- 3) - (a)}{a - 3}$

Step 3

Factor $- 1$ out of $- 1 (- 3) - (a)$ .

$\frac{- 1 (- 3 + a)}{a - 3}$

Step 4

Reorder terms.

$\frac{- 1 (a - 3)}{a - 3}$

Step 5

Cancel the common factor.

$\frac{- 1 (a - 3)}{a - 3}$

Step 6

Divide $- 1$ by $1$ .

$- 1$
