# How do you solve and write the following in interval notation: x(x − 1)(x + 5) >0?

Jun 8, 2017

$x \in \left(- 5 , 0\right) \cup \left(1 , \infty\right) \subset \mathbb{R}$

#### Explanation:

The zeroes are $- 5 , 0 , 1$

The signals are $-$ $0$ $+$ $0$ $-$ $0$ $+$

$- 5 < x < 0 \mathmr{and} x > 1$
