You can put this solution on YOUR website!

First you need to know that a quadratic equation is a polynomial equation of the second+degree.
The general form is y+=+ax%5E2%2Bbx%2Bc+ (x^2 = x squared)
so if the equation has a squared term, it's a quadratic
in your case:
+y=5x%2Bx%5E2+ yes, it's a quadratic
