Given, (1+m)x^2 + 2mcx + c^2 - a^2 = 0

We know that b^2 - 4ac = 0

                        (2mc)^2 - 4(1+m^2)(c^2 - a^2) = 0

                        4m^2c^2 - 4(c^2 - a^2 + m^2c^2 - m^2a^2)  = 0

                        4m^2c^2 - 4c^2 + 4a^2 - 4m^2c^2 + 4m^2a^2 = 0

                        4c^2 = 4a^2 + 4a^2m^2 

                        4c^2 = 4a^2(1+m^2)
                 
                         c^2 = a^2(1+m^2).


                          LHS = RHS..


Hope this helps!
