Question

(x - 1)(x+5)>0 solve the inequation ​

Answer 1

Answer:

(- ∞, -5) ∪ (1, ∞)

Step-by-step explanation:

First, both factors are positive:  

x - 1 > 0, x > 1 and x + 5 > 0, x > - 5 ===> x > 1

Second, both factors are negative:

x - 1 < 0, x < 1 and x + 5 < 0, x < - 5 ===> x < - 5  

The answer is x < - 5 or x > 1  

(- ∞, -5) ∪ (1, ∞)
