Anyone here good at math? I havn't used the quadratic equation in years and having a heck of a time trying to solve this. The basic equation: Rt=Ro * [1 + AT + BT^2] I am trying to solve for T. I know Rt, Ro, A and B If I simplified correctly: Rt=RoBT^2 + RoAT + Ro I would then take Ro and multiply it times B and then times A to simplifiy it again. Then use the quadratic equation. Problem is when I do this my answers don't come out correctly? Anyone see what I'm doing wrong?
