5x^4=5x Can you please help

5x^4=5x x^4 - x = 0 x(x^3 - 1) = 0 x = 0 or x^3 = 1 x = 0 or x = 1 There are also two complex roots, but I don't think you have studied that. Let me know if you did.

Yes I have but how to you find them

the above factor of x^3 - 1 factors to (x-1)(x^2 + x + 1) the x-1 = 0 gave us x = 1 x^2 + x + 1 = 0 x = (-1 ±√-3)/2 or x = (-1 ± i√3)/2

Thank you
