[QUOTE="Panphobia, post: 4520157, member: 487822"] [h2]Homework Statement [/h2] [ATTACH=full]164325[/ATTACH] [h2]The Attempt at a Solution[/h2] So when I started this question, I knew that 2r +3 > 0 in order for this whole thing to work so r > -3/2, and I know that if the middle term has to be more than 0, than only one more of the others is going to be negative, for the first term i found that r < 4/3 and the third was r < 2, so I know that the answer should be (4/3, 2), but how do I prove that algebraically?
