This is my polynomial:

5x^5 - 6x^4 - 24x^3 + 20x^2 + 7x - 2 = 0

I found the rational roots and from that found some factors:

(x-1)(5x-1)(x +2)

I don't know how to find the rest of the solutions...

Please don't just give me an answer, tell me what you did to get from the factors found from rational roots to the solutions of the equation.

Thanks
