X²-6x+4=0
transpose 4 to the other side of equation
x²-6x= -4
make the equation a perfect square trinomial
divide -6 by 2, and square the product
(-3)² = 9
x²-6x+9= -4+9
x²-6x+9= 5
find the factors of the equation
(x-3)² = 5
find the square root of the both side
√(x-3)² = √5
x-3 = √5 or -√5
transpose -3
x= 3 √5 or x= 3 -√5
