The discriminant is b^2-4ac
I won't do all the work for you, but figure that number out.
-If its positive, theres two solutions
-If its negative there are no solutions
-If its zero theres one solution.
Compute the value of the discriminant and give the number of real solutions to the quadratic equation.
