Can You Crack the Quadratic Formula: Unraveling the Mystery of x = b±√(b^2-4ac)/2a - postfix
While the quadratic formula can solve most quadratic equations, there are some exceptions. For example, if the expression inside the square root is negative, the solution will be complex numbers. The quadratic formula is not applicable to quadratic equations with a discriminant (the expression inside the square root) equal to zero.
