Let the solution set of inequality f (x) ≥ 0 be [1,2], and the solution set of inequality g (x) ≥ 0 be an empty set Let the solution set of inequality f (x) ≥ 0 be [1,2], and the solution set of inequality g (x) ≥ 0 be an empty set, then if the solution set of inequality f (x) / g (x) > 0 is complete, there is another answer

Let the solution set of inequality f (x) ≥ 0 be [1,2], and the solution set of inequality g (x) ≥ 0 be an empty set Let the solution set of inequality f (x) ≥ 0 be [1,2], and the solution set of inequality g (x) ≥ 0 be an empty set, then if the solution set of inequality f (x) / g (x) > 0 is complete, there is another answer

Because f (x) / g (x) > 0
So f (x) g (x) > 0
And because the solution set of G (x) ≥ 0 is an empty set, that is g (x)
