for question 9(ii) u have the found 2 roots = 1-√2i and 1+√2i so the 2 factors of the polynomial that has been found are (u-(1-√2i)) and (u-(1+√2i)) if u multiply these factors together u will get a quadratic equation of u^2-2u+3 now u have the polynomial equation as u^4 + u^2 + 2u + 6....u or... -

hey... C40H82 -------> C16H34 + C24H48 a good way of explaining this question is to see how many bonds u have before the reaction and how many bonds u have after the reaction for example... before the reaction we have 39 C-C bonds and 82 C-H bonds...after the reaction we have 15+22 = 37 C-C...
