Solve

by completing the square

Step 1: Move the constant term to the right hand side.

Step 2: Multiply both sides by

Step 3: Divide the coefficient on the first order term by 2, square the result, and add that result to both sides:

Step 4: Determine and apply the LCD in the RHS:

Step 5: Factor the perfect square trinomial in the LHS:

Step 6: Take the square root of both sides. Consider both positive and negative roots:

Step 7: Add the opposite of the constant term in the LHS to both sides:

Simplify if possible and you are done. You can find your own example to use.
