Find Find roots 7x^3-28x^2+28x-56

Your problem `->` Find roots 7x^3-28x^2+28x-56


If a polynomial has integer coefficients, then every rational zero will have the form `p/q`, where `p` is a factor of the constant and `q` is a factor of the leading coefficient.

p = factor of `56`

`:. p = +-1,+-2,+-4,+-7,+-8,+-14,+-28,+-56`

q = factor of `7`

`:. q = +-1,+-7`

Find `+-p/q`, these are the possible roots
