The complete question is

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

Step 1: x2 +4x= 6

Step 2: x2 +4x+4=6+4

Step 3: (x +2)^2=10

What are the next 3 steps?​

we have

step 4

Take square root both sides


√((x+2)^2) =√(10)

step 5

Simplify


x+2=\pm√(10)

step 6

Solve for x

subtract 2 both sides


x=-2\pm√(10)


x_1=-2+√(10)


x_2=-2-√(10)
