In conics, if this value is less than 0, a circle or ellipse forms.
In conics, if this value is less than 0, a circle or ellipse forms. If this value is 0 in cubic functions, there is one root of multiplicity 2. If this value is positive in a quadratic equation, then there are two real solutions; and the formula for finding this value in a quadratic equation is b squared minus four a c. For 10 points, name this value which can be used to determine the nature of roots of a function.
