Set up the expression in factored form, leaving blanks for the numbers that are not yet known.
At this point, you need to find two numbers - one for each blank. By looking at the original expression, a few clues can be gathered that will help find the two numbers. The product of these two numbers will be equal to the last term of the original expression (1, or c in the standard quadratic formula), and their sum will be equal to the coefficient of the second term of the original expression (2, or b in the standard quadratic formula). Because their product is positive (1) and the sum is positive, that must mean that they both have positive signs.
Now, at this point, test a few different possibilities using the clues gathered from the original expression. In the end, it's found that the only numbers that work are 1 and 1, as the product of 1 and 1 is 1, and sum of 1 and 1 is 2. So, this results in the expression's factored form looking like...
From here, set the binomial equal to zero and solve for

the middle term coefficient, when divided by two and squared, results in the coefficient of the last term.
Complete the square for this particular function is as follows.
First identify the middle term coefficient.
Now divide the middle term coefficient by two.
From here write the function with the perfect square.
When simplified the new function is,
Since the term is positive, the parabola will be opening up. This means that the function has a minimum value at the vertex. To find the value of the vertex set the inside portion of the binomial equal to zero and solve.
From here, substitute the the value into the original function.
Therefore the minimum value occurs at the point 
.
