Question

(x+15)(x-12)(x+10)>0
___A Solution set is {x1 }
___B The solution is all real numbers
___C No solution

Answer 1

The solution to the inequality above is a
solution set ox values satisfying the following conditions:
-15 < x < -10;
or
x > 12

Therefore it is not the entire set of real numbers. If I were to choose from the multiple choices I would choose (A) even though it does not say what values were contained in the set.
