Homework Answered Due Today, 11:59 PM
Solve the inequality and enter the solution set using interval notation without any blank spaces. Use infinity or -infinity in the
solution set, if needed. Use a capital letter U for the union symbol, if needed.
$(x - 5)(x + 4)(x - 1) < 0$

Hint
Set the inequality equal to zero to find the boundary numbers. Then test a point from each interval formed by these solutions in
inequality. We can also use the graph to determine the solutions.
Do not enter any blank spaces in your answer. Spell out infinity (if needed) in your solution set.
