Does any one know how to identify the roots of a quadratic equation if the equation is really long?

P.S. If you need I will provide an example.

Please do.

As far as solving it by graphing, it is pretty self evident. Graph your equation and wherever the curve meets the x axis is a root.

What do you mean, "if the equation is really long"? By definition, a quadratic can only have 3 terms. It can't be any longer than that. All quadratic equations take the form of:

ax^2 + bx + c = 0

To solve this, use the quadratic equation, or, if you have a graphing calculator, graph it and find out when it crosses the x-axis (x = 0).

"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."
