A quadratic equations is an equation of the form ax^2 + bx + c=0.
There are several other ways of solving a quadratic equation. In this document, we discuss how one can use the Quadratic formula to determine the type of solutions in a quadratic equation. The discriminant (D) is given by: D= b^2 - 4ac
The Discriminant tells us whether the equation will have one real solution or two real solutions or two imaginary solutions in a quadratic equation.
If D=0 , then the quadratic equation has only one real solution
If D>0 , then the quadratic equation has two real solution
If D<0 , then the quadratic equation has only one real solution
