The first three steps of completing the square to solve the quadratic equation x2 +4x-6=0

Step-by-step explanation:

1.  Move the 6 to the other side:   x^2 +4x                        =6

2.  Square half the coefficient of the x term:  (4/2)^2 = 4

3.  Add this 4, and then subtract this 4, from x^2 + 4x:

     x^2 +4x + 4 - 4                       =6

4.  Rewrite this perfect square as the square of a binomial:

      (x + 2)^2   -   4   = 6

5.  Add 4 to both sides:    (x + 2)^2 =  10

6.  Find the sqrt of both sides:  x + 2 = √
