If you aren't dealing with algebra, such as x2+3x+21, then completing the square wont be able to solve the porblem, however if you are using algebra, and you cannot factorise, then completing the square will always work
The square root.
algebra
Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by several methods including factoring, graphing, using the square roots or the quadratic formula. Completing the square will always work when solving quadratic equations and is a good tool to have. Solving a quadratic equation by completing the square is used in a lot of word problems.I want you to follow the related link that explains the concept of completing the square clearly and gives some examples. that video is from brightstorm.

A quadratic equation can be solved by completing the square which gives more information about the properties of the parabola than with the quadratic equation formula.
The square root.
The quadratic formula can be derived by used a method called completing the square. It's like using algebra to solve for x. The process is explained the related link "Derivation of Quadratic Formula".
Completing the square would be the same as "Finding the square root" So an example would be 16. 16 is a perfect square so it would reduce to 4.

Completing the square is a method used to solve a quadratic function. This is a handy method when there are two instances of the same variable in the function.
I believe by completing the square.
I use algebra to figure square footage, cubic footage, and angles when building, It is very important.
the problem is not proper to slove. I just want to suggest to follow the related link that explains the concept of completing the square clearly.
