The remainder obtained when the polynomial x+x^3 +x^9+x^27+x^81+x^2^243 is divided by x^2-1 is: The answer is given as 6x but I dont know how to proceed. Thanks

Shouldn't it be: ? Anyway, when divided by : , where Q(x) is the quotient, R(x) is the remainder. Its degree can be at most 1, so and Now but also Now you've got 2 simultaneous equations, solving for a and b gives a=6, b=0 so R(x)=6x.
nopes . x^2^243 only anyways, will try with your method and c if i can get an answer.
