<u><em>The complete question is</em></u>
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
![\sqrt{(x+2)^2} =\sqrt{10}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x%2B2%29%5E2%7D%20%3D%5Csqrt%7B10%7D)
step 5
Simplify
![x+2=\pm\sqrt{10}](https://tex.z-dn.net/?f=x%2B2%3D%5Cpm%5Csqrt%7B10%7D)
step 6
Solve for x
subtract 2 both sides
![x=-2\pm\sqrt{10}](https://tex.z-dn.net/?f=x%3D-2%5Cpm%5Csqrt%7B10%7D)
![x_1=-2+\sqrt{10}](https://tex.z-dn.net/?f=x_1%3D-2%2B%5Csqrt%7B10%7D)
![x_2=-2-\sqrt{10}](https://tex.z-dn.net/?f=x_2%3D-2-%5Csqrt%7B10%7D)
Because you know how much money you will receive in interest every x amount of time with no variability.
