Re: HSC 2015 4U Marathon - Advanced Level
Are allowed to be non-real complex numbers? Do you mean , or ? And is the root, or is it ? It is possible to have all roots have modulus less than 1 and have be unsatisfied, e.g. for some real such that is not real (clearly such exists). In this case, does not make sense since is not real.
I think we need some clarification.
