Question 604680
<pre>
    _
|1-<font face="symbol">Ö</font>2|
       _
Since <font face="symbol">Ö</font>2 is greater than 1, then
   _
1-<font face="symbol">Ö</font>2 

is negative, so to make it positive, we have to multiply

it by -1:
      _
-1(1-<font face="symbol">Ö</font>2)
      _
-1 + <font face="symbol">Ö</font>2

But if we don't like a negative sign in front we can change
it to:
 _
<font face="symbol">Ö</font>2 = 1
