Step 1: Divide the entire polynomial by the coefficient on the term.

Step 2: Divide the coefficient on the term by 2: Result:

Step 3: Square the result of step 2: Result:

The result of step 3 is the value of the constant term required to make a perfect square, therefore =>

can be multiplied by 4 to reverse the effects of step 1, resulting in which then factors to
