Method and examples
Expansion: `X+1/X` To `X-1/X` (with all intermediate solution steps)
 
1. If  =  then find  
  1. If `X+1/X=2` then find `X-1/X`
  2. If `X+1/X=2` then find `X^2+1/X^2`
  3. If `X-1/X=6` then find `X^2+1/X^2`
  4. If `X-1/X=6` then find `X^2-1/X^2`
  5. If `X-1/X=6` then find `X^3+1/X^3`
  6. If `X-1/X=6` then find `X+1/X`
  7. If `X^2+1/X^2=23` then find `X+1/X`

2. If  =  and  =  then find    
  1. If `X+Y=5` and `XY=6` then find `X^2+Y^2`
  2. If `X+Y=5` and `XY=6` then find `X^2-Y^2`
  3. If `X+Y=3` and `X-Y=15` then find `X^2+Y^2`

3. If  =  and  =  then find  
  1. If `X+Y+Z=9` and `X^2+Y^2+Z^2=29` then find `XY+YZ+ZX`
  2. If `X^2+Y^2+Z^2=29` and `XY+YZ+ZX=-14` then find `X+Y+Z`
