You can put this solution on YOUR website! Find all complex solutions of the equation
(moved from Algebra:Trigonometry-Basics to Algebra:Complex Numbers)
x^4 - x^3 + x^2 - x = 0
(x^2 + 1)(x^2 - x) = 0 (by FOIL x^4 - x^3 + x^2 - x = 0)
(x^2 + 1)(x - 1)x = 0
solutions: x = 0, x - 1 = 0, x^2 + 1 = 0
x - 1 = 0 --> x = 1
x^2 + 1 = 0 --> x^2 = -1 --> x = + - sqrt(-1) --> x = +- i
2 real solutions being: 0 and 1
2 complex solutions being: +- i which in complex form of a + bi would be written as 0 +- i
