Question 527982: An equation in standard form is ax^2+bx+c=0
Solve equation by completing the square and leaving all variables as is. What are the steps to solving this question? The answer should be x=-bħsqrtb^2-4ac
______________
2a
Answer in words: x is equal to negative b plus or minus square root of (b^2-4ac) all right side of equation divided by 2a. Show all steps that change ax^2+bx+c=0 into the answer.

You can put this solution on YOUR website!
First, divide both sides by a (so that completing the square will be easier).



Now complete the square:

where C is some unknown value. If you expand and equate the constant terms, you will find that



Hence,

, take square root of both sides.
