For equal roots
b²-4ac > 0
Because If we draw the graph of that line then function has 2 unequal real roots, and the parabola intersects x-axis at 2 points.

Sir, here the roots are rational but not equal(successional).Then how D will equal to 0.
?????
????
i think
there are two possibility of getting two roots as rational numbers.
or real numbers
1) Getting two distinct real roots
2)Two equal real roots
hope you get it now
if you got it tell me
