I told you, use the discriminant. If discriminant = 0, there's only 1 root( -b/2a ), otherwise you need to do the complete formula. That iteration wastes so much computation time it makes me cry.

I remember the quad eq. I still have the program I created for my TI-84 Plus to solve it for me. I just plugged in A, B, and/or C and it outputted the squared and square rooted value.

So basically it's as hard to leave the skid zone as it is the friend zone?
