Question

Solve. Provide answers in interval notation.
-$(x-8)(x-10)(x+5)<0$
A) $(-\infty,-8) \cup(5,10)$
B) $(-10,-8) \cup(5, \infty)$
C) $(-8,-5) \cup(10, \infty)$
D) $(-\infty,-5) \cup(8,10)$

Quizplus · Accepted Answer

The correct intervals are found by solving the inequality $(x-8)(x-10)(x+5)<0$. The critical points are $x = -5$, $x = 8$, and $x = 10$. Testing values between and outside these points shows that the function is negative in the intervals $(-\infty,-5)$ and $(8,10)$.
