Start with the given equation:

If the lead coefficient is other than 1, divide by the lead coefficient.

Move the constant term to the RHS:

Divide the first term coefficient by 2 and square the result. Add this result to both sides. Minus 6 divided by 2 is minus 3. Minus 3 squared is 9. Add 9 to both sides:

Factor the perfect square in the LHS:

Take the square root of both sides:
