Best ResponseYou've already chosen the best response.02X^4 5x^3x^2  6x+4 it has two sign changes and my teacher told me to divide it by and even number so what next im stuck at 2 and 1

Best ResponseYou've already chosen the best response.0are you sure your function is right because solution are irrational http://www.wolframalpha.com/input/?i=2%28x%29%5E45%28x%29%5E3%28x%29%5E26%28x%29%2B4

Best ResponseYou've already chosen the best response.0there are 2 sign changes in your function which mean , you have 2 solution or an even number lower  O solution .

Best ResponseYou've already chosen the best response.02x^4−5x^3−x^2−6x+4 this is how to do this: there are two sign changes which mean, there are two or 0(even number lower) positive solution. to find negative soloution, invert the sign of the term with odd power 2x^4+5x^3  x^2 + 6 x+4 which mean it has either 2 or 0 solution negative solution
