Find all roots of polynomial using Bairstow method
f(x) =
Initial `r` = , `s` =
  1. `f(x)=x^4-3x^3+3x^2-3x+2` and `r=0.1,s=0.1`
  2. `f(x)=9x^4+12x^3+13x^2+12x+4` and `r=-1,s=-1`
  3. `f(x)=x^3-x^2-x+1` and `r=-1,s=-1`
  4. `f(x)=x^4-2x^3+6x^2-2x+5` and `r=-1,s=-1`
  5. `f(x)=0.7x^3-4x^2+6.2x-2` and `r=-1,s=-1`
