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.

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.

It comes from completing the square of a general quadratic. Many people believe Brahmagupta first solved this in 628 AD.

Surds are irrational square root numbers that cannot be solved but they can be simplified. For example the square root of 12 can be simplified to 2 times the square root of 3.

It is -5*sqrt(X - 15) which is an expression which cannot be simplified nor solved.

It is an expression, in a variable x. Since it is not an equation, it cannot be solved.

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.

No, they cannot. Sorry! Hope I helped you figure out your math problem!

NO

The roots of any quadratic equation can be found by either method. Which of the two you use may depend on nothing more than your preferences (or exam instructions!). There is never a need to use both methods since if you have used one you have the answer so why bother with the other.

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.
