Discriminant of Quadratic Equation


Quadratic equations are those algebraic equations of the form $ax^2+bx+c$, where $a$, $b$, and $c$ are constant values. The discriminant of a quadratic equation is calculated using the formula $D=b^2-4ac$, and it helps us to determine how many roots an equation of this type has. When $D>0$ the equation has two real roots, when $D<0$ the equation has no real roots, and when $D=0$ the equation has a repeated real root.
