How do you solve #x^2 - 6x + 4 = 0# by completing the square ?
Add a constant to both sides such that the left hand side is a perfect square.
In order to complete the square, we must determine what on the left hand side could be squared to give us the given
Thus, our squared binomial will take the form
In order to get this polynomial on the left hand side, we add 5 to both sides .
From here, we can square root the left hand side.
Then adding 3 to both sides:
