2.2 Solving x2-2x-1 = 0 by Completing The Square . Add 1 to both side of the equation : x2-2x = 1. Now the clever bit: Take the coefficient of x , which is 2 , divide by two, giving 1 , and finally square it giving 1. Add 1 to both sides of the equation : On the right hand side we have : 1 + 1 or, (1/1)+ (1/1)Two numbers r and s sum up to 2 exactly when the average of the two numbers is \frac{1}{2}*2 = 1. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C.
