We are doing a review of algebra 2 and I really need some help. I have a new teacher and I never learned it the way he taught us. He doesn't let us use calculators. So I was wondering if some of you could please help me with some equations! Solve the following polynomial inequalities.
4. -2x^2-4x+2x^3 <0
If anyone could help me with these it would be great. And yes I have tried and been sitting here for an hour stuck on them so don't think I didn't even try. Thank you!
