Question 66236
<pre><font size = 5><b>
     <font face = "symbol">æ</font>     cx     x <font face = "symbol">ö</font>	
cx ũ <font face = "symbol">į</font>1 - ———— - ———<font face = "symbol">ũ</font> 
     <font face = "symbol">č</font>      c     c <font face = "symbol">ø</font>

Write the cx and the 1 over 1

 cx    <font face = "symbol">æ</font> 1     cx     x <font face = "symbol">ö</font>	
———— ũ <font face = "symbol">į</font>——— - ———— - ———<font face = "symbol">ũ</font> 
  1    <font face = "symbol">č</font> 1      c     c <font face = "symbol">ø</font>

The LCD in the parentheses is c.
The last two fractions already
have c for their denominators,
so multiply top and bottom of
1/1 by c:

 cx    <font face = "symbol">æ</font> 1·c     cx     x <font face = "symbol">ö</font>	
———— ũ <font face = "symbol">į</font>————— - ———— - ———<font face = "symbol">ũ</font> 
  1    <font face = "symbol">č</font> 1·c      c     c <font face = "symbol">ø</font>

 cx    <font face = "symbol">æ</font> c     cx     x <font face = "symbol">ö</font>	
———— ũ <font face = "symbol">į</font>——— - ———— - ———<font face = "symbol">ũ</font> 
  1    <font face = "symbol">č</font> c      c     c <font face = "symbol">ø</font>

Combine fractions in parentheses
all over the LCD of c

 cx    <font face = "symbol">æ</font> c - cx - x <font face = "symbol">ö</font>	
———— ũ <font face = "symbol">į</font>————————————<font face = "symbol">ũ</font> 
  1    <font face = "symbol">č</font>      c     <font face = "symbol">ø</font>

Invert the second fraction and
change the division to multiplication:

 cx    <font face = "symbol">æ</font>      c     <font face = "symbol">ö</font>	
———— Ũ <font face = "symbol">į</font>————————————<font face = "symbol">ũ</font> 
  1    <font face = "symbol">č</font> c - cx - x <font face = "symbol">ø</font>

Multiply numerators and denominators:

         cēx     
     ———————————— 
      c - cx - x
