Use completing square to find the solutions of the equations.
a. x^2+2x-2=0 b. x^2-6x=1
x^2+2x=2 (move -2 to right hand side)
x^2+2x+1=2+1 (add 1 on both side, square of the half of the coefficient of x if 1)
(x+1)^2=3 (factoring left hand side)
x^2-6x+9=1+9 (add 9 on both side, square of the half of the coefficient of x if 9)
(x-3)^2=10 (factoring left hand side)
Thank you :-)
