Web2.2 Solving x2-6x+2 = 0 by Completing The Square . Subtract 2 from both side of the equation : x2-6x = -2. Now the clever bit: Take the coefficient of x , which is 6 , divide by two, giving 3 , and finally square it giving 9. Add 9 to both sides of the equation : On the right hand side we have : -2 + 9 or, (-2/1)+ (9/1) Web26. 1.X2 -2x -4 =0 2.3x2 +2x -21 =0 3.x2 -6x +21 =0 4.5x2 + 26x + 5=0 5.7x2-2x =1. Answer: 5.
