Question 198: why are there usually two solutions in quadratic equations?
Answer by ichudov(507)   (Show Source):
You can put this solution on YOUR website! Good question. A graph of a quadratic equation is a parabola, and because it has two wings pointing inthe same direction, a parabola could cross the x axis twice. By the way, cubic equations can have up to 3 different solution, quartic (4th power) equations can have up to 4 solutions, etc.
