Solve each of the following equations by using the method of completing the square:
x2 - 6x + 3 = 0
Given: x2 - 6x + 3 = 0
x2 - 6x = - 3
x2 - 2.x.3 + 32 = - 3 + 32 (adding 32 on both sides)
(x - 3)2 = - 3 + 9 = 6 using a2 - 2ab + b2 = (a - b)2
(taking square root on both sides)
Hence the roots of equation are
