Just by graphing? Use general solution of the quadratic equation to find the roots and then draw the graph. If computing the discriminant gives a negative number, then no real roots can be shown.
The x-intercepts will be two irrational values.
zeros or roots are and ;
or and . Those are exact irrational real roots.
