Explanation:
Discriminant of a Quadratic.
The number
The discriminant reveals what type of roots the equation has. Note: b^2 – 4ac comes from the quadratic formula.

#color(blue)(b^2 −4ac = 0, " There is one real root. "# 
#color(green)(b^2 −4ac > 0, " There are two real roots. "# 
#color(red)(b^2  4ac < 0, " If the discriminant of a quadratic function is less than zero, that function has no real roots, and the parabola it represents does not intersect the xaxis."#
