The quadratic formula is the mathematical formula used to find the two real and distinct, real and identical, or imaginary and distinct roots of a quadratic equation of the form ax^2+bx+c.
The quadratic formula is -b±(b^2-4ac)/2a and the discriminant which determines what type of roots the equation will have is b^2-4ac.
|Value of b^2-4ac||Type of solution|
|> 0||Real and distinct roots|
|= 0||Real and identical roots|
|< 0||Imaginary and distinct roots|
