Best ResponseYou've already chosen the best response.1this is the Descartes rule of signs which i've only got a vague memory of . I'll see if I can find a website for you. Or maybe someone who remembers it will come along..

Best ResponseYou've already chosen the best response.1now you find f(x) and count the sign changes again f(x) = (x)^6 −( x)^5 − (x)^4 + 4(x)^3 − 12(x)^2 + 12 = x^6 + x^5  x^4  4x^3 12x^2 + 12  2 changes of signs
