# Is completing the square always the best method?

There are multiple ways to solve quadratic equations, so I wouldn't say that completing the square is always the best approach.

- Graphing to visually determine the locations of the x-intercepts; 2) Factoring; 3) Substitution; 4) Square Completion; 5) Quadratic Formula

There is no set order for these techniques.

Completing the square is not always the best method for solving quadratic equations. It can be useful in some cases, particularly when the quadratic equation is given in a standard form and factoring is difficult. However, for certain equations, factoring, using the quadratic formula, or graphing may be more efficient or appropriate methods. The choice of method depends on the specific equation and the preferences of the solver.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
