SUMMARY
The equation (z+1)^5 = z^5 can be solved using roots of unity. By rewriting the equation as 1 = ((z+1)/z)^5, the solutions can be derived from the fifth roots of unity. The specific roots are given by w = exp(i*2k*pi/5) for k = 1, 2, 3, 4, leading to the solutions z = 1/(1-w). This method provides a systematic approach to finding all complex solutions to the equation.
