Best Answer

That the discriminant of the quadratic equation must be greater or equal to zero for it to have solutions.

If the discriminant is less than zero then the quadratic equation will have no solutions.

More answers

The equation must be written in the form ( ax^2 + bx + c = 0 ), where ( a \neq 0 ). This is the standard form of a quadratic equation. If the equation is not in this form, you may need to rearrange it before applying the quadratic formula.
