hcf of x^2-1 & ax^3-b(x+1) is (x-1) hence (x-1) is a factor of both polynomials
on dividing ax^3-b(x+1) from (x-1) we get remainder a-2b
(x-1) to be factor of ax^3-b(x+1) remainder should be zero
a-2b = 0
a = 2b
on dividing ax^3-b(x+1) from (x-1) we get remainder a-2b
(x-1) to be factor of ax^3-b(x+1) remainder should be zero
a-2b = 0
a = 2b
