I'm not sure I understand the question.
We can try completing the square:
x%5E2+-+2x+=+4
x%5E2+-+2x+%2B+1++=+4+%2B1
%28x-1%29%5E2+=+5
sqrt%28%28x-1%29%5E2%29+=+sqrt%285%29%0D%0A%7B%7B%7Babs%28x-1%29+=+sqrt%285%29
+x-1++=+sqrt%285%29 and -%28x-1%29+=+sqrt%285%29
+x+=+sqrt%285%29+%2B1 and x+=+-sqrt%285%29+%2B+1
Maybe this is what they are asking for?
Hope this helped.
