If t^2 - 1 is a factor of at^3+t^2 - 2t + b, find the values of a and b

If t²-1 is a factor, then both t-1 and t+1 are factors.

According to the remainder theorem, when a binomial x-a is a factor of a polynomial p(x), then p(a)=0.

If t-1 and t+1 are factors of p(t)=at³+t²-2t+b, then p(1)=0 and p(-1)=0.

Im not that good with division but i think 5 is -6but dont quote me on thatim not the best in division but thats my answer
