Question

$$\frac{a^{2}}{a+3}-\frac{9}{a+3}$$

Evaluate

$a-3$

Short Solution Steps

Since $\frac{a^{2}}{a+3}$ and $\frac{9}{a+3}$ have the same denominator, subtract them by subtracting their numerators.

$$\frac{a^{2}-9}{a+3}$$

Factor the expressions that are not already factored in $\frac{a^{2}-9}{a+3}$.

$$\frac{\left(a-3\right)\left(a+3\right)}{a+3}$$

Cancel out $a+3$ in both numerator and denominator.

$$a-3$$

Factor

$a-3$
