Well, if I take the product of two things and it's less than zero, that means that they have to have different signs, either one's positive and the other is negative or one's negative and the other's positive. So we have two situations. So we could say either, either three x to the fourth is greater than zero and, and two x minus five is less than zero. So that's one situation. I'll do this in a different color. Or, and I'll do this one in a different color, three x to the fourth is less than zero and two x minus five is greater than zero. Actually, let me stay on the second case first.
