Advice Recall the binomial theorem and use this to answer each part For example, if we want to know the coefficient of the xi term in (a+bx)n then we look at the binomial theorem and can see that the coefficient will be nCi∗a(n−i)∗bi Score: 0/6 Total 0/6 Move to the next questionTry another question like this oneReveal answers
