 x ^ 2  2 x  6 = 4
Eliminate the absolute value :
x ^ 2  2 x  6 = 4
OR
x ^ 2  2 x  6 =  4
Your must solve both equations.
In google type:
quadratic equation online
When you see list of results click on:

When page be open in rectangle type:
x ^ 2  2 x  6 = 4
and click option: solve it!
You will see solutions of equation :
x ^ 2  2 x  6 = 4

Then in rectangle type:
x ^ 2  2 x  6 =  4
and click option: solve it!
You will see solutions of equation :
x ^ 2  2 x  6 =  4

Equation :
 x ^ 2  2 x  6  = 4
has 4 solutions :
1 + sqrt ( 11 )
1  sqrt ( 11 )
1 + sqrt ( 3 )
and
1  sqrt ( 3 )
