You can put this solution on YOUR website!
.
If you don't know what a discriminant is or how to use it to solve the problem, then
read the lesson Introduction into Quadratic Equations in this site.

If you do know, then calculate it on your own.

Making calculating for you or instead of you is not a tutor's work.

It is your work.

Find the Disc
Disc = b^2 - 4ac in the form ax^2 + bx + c
----
If the Disc >= 0 the solutions are real.
==============
It's just arithmetic.
