$f (x) = \frac{x^{2} + 5 x}{x - 2}$

Step 1

Rewrite the function as an equation.

$y = \frac{x^{2} + 5 x}{x - 2}$

Step 2

Factor $x$ out of $x^{2} + 5 x$ .

Step 2.1

Factor $x$ out of $x^{2}$ .

$y = \frac{x \cdot x + 5 x}{x - 2}$

Step 2.2

Factor $x$ out of $5 x$ .

$y = \frac{x \cdot x + x \cdot 5}{x - 2}$

Step 2.3

Factor $x$ out of $x \cdot x + x \cdot 5$ .

$y = \frac{x (x + 5)}{x - 2}$

$y = \frac{x (x + 5)}{x - 2}$
