Assuming you really meant, , you want to Complete The Square and adjust to format. Thee term to both ADD and SUBTRACT on the right-side member is . Doing this will allow you to obtain a portion of right-side expression which is a perfect square, and an added or subtracted constant term.



You finish the work.
For further help and instruction, look at the and study the lesson, "What is Completing The Square? With Visual Explanation" and maybe also "Completing the Square to Solve General Quadratic Equation". Find these in the lessons link in my profile.
