2. Completing the square involves the same process for each problem
Completing the square involves the same process for each problem. Therefore, we can perform the process once with variable in place of all the numbers, and derive a formula to save the effort of completing the square to solve quadratic equations. However we will still need the skill to re-write quadratic equations in vertex form.
