Question Number 55888 by behi83417@gmail.com last updated on 05/Mar/19
   a=1+b+b^2      b=1+c+c^2      c=ab+a^2 +b^2      solve for :  a,  b,  c.
$$\:\:\:\boldsymbol{\mathrm{a}}=\mathrm{1}+\boldsymbol{\mathrm{b}}+\boldsymbol{\mathrm{b}}^{\mathrm{2}} \\ $$$$\:\:\:\boldsymbol{\mathrm{b}}=\mathrm{1}+\boldsymbol{\mathrm{c}}+\boldsymbol{\mathrm{c}}^{\mathrm{2}} \\ $$$$\:\:\:\boldsymbol{\mathrm{c}}=\boldsymbol{\mathrm{ab}}+\boldsymbol{\mathrm{a}}^{\mathrm{2}} +\boldsymbol{\mathrm{b}}^{\mathrm{2}} \\ $$$$\:\:\:\boldsymbol{\mathrm{solve}}\:\boldsymbol{\mathrm{for}}\::\:\:\boldsymbol{\mathrm{a}},\:\:\boldsymbol{\mathrm{b}},\:\:\boldsymbol{\mathrm{c}}. \\ $$

no real solution   ((a),(b),(c) ) ∈{ (((−.209±.203i)),((−.397±.985i)),((−.927∓1.15i)) ) ,  (((.442±1.73i)),((−1.35∓1.02i)),((−.841±1.49i)) ) ,  (((.703±.458i)),((−.0453±.504i)),((−.230±.932i)) ) ,  (((−.936∓2.09i)),((−1.21±1.48i)),((−.00212±1.48i)) ) }  if needed I′ll post more digits
