Tap for more steps...

Step 1.1

Factor $x$ out of $x^{3}$ .

$p (x) = x \cdot x^{2} - x p \cdot - 4$

Step 1.2

Factor $x$ out of $- x p \cdot - 4$ .

$p (x) = x \cdot x^{2} + x (- 1 p \cdot - 4)$

Step 1.3

Factor $x$ out of $x \cdot x^{2} + x (- 1 p \cdot - 4)$ .

$p (x) = x (x^{2} - 1 p \cdot - 4)$

Step 2

Rewrite $- 1 p$ as $- p$ .

$p (x) = x (x^{2} - p \cdot - 4)$

Step 3

Multiply $- 4$ by $- 1$ .

$p (x) = x (x^{2} + 4 p)$
