Completing the square:
Step 1: Add the additive inverse of the constant term to both sides.
Step 2: Multiply both sides by the reciprocal of the lead coefficient.
Step 3: Divide the 1st degree term coeficient by 2, square the result, and add that result to both sides. Combine terms in the LHS.
Step 4: Factor the resulting perfect square trinomial in the RHS.
Step 5: Take the square root of both sides, considering both positive and negative roots.
Step 6: Add the additive inverse of the RHS constant to both sides.
