Quizplus · Accepted Answer

The quadratic formula can solve any quadratic equation, regardless of its form, because it directly uses the coefficients from the equation. Completing the square is a method that can also be used to solve any quadratic equation, as it essentially transforms the equation into a form that can easily be solved by taking square roots. Factoring, on the other hand, only works when the quadratic equation can be factored into the product of two binomials, which is not always possible. Finding square roots directly is only applicable in specific cases where the quadratic equation is already in a perfect square form or can easily be manipulated into one.
