using quadratic formula solve
x^22x6 = 4. and answer have to be 1+sqrt3, 1+sqrt11 i just not get how to get this.

 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:

has 4 solutions :
1 + sqrt ( 11 )
1  sqrt ( 11 )
1 + sqrt ( 3 )
and
1  sqrt ( 3 ) 
thank you very much the site be very very helpful i try to find site like that yesterday and i not find thanks very much.
