If x+1 and x-1 are the factors of the polynomial ax^3 + x^2 - 2x +b, find the values of a and b

The polynomial remainder theorem says that dividing a polynomial by leaves a remainder of if is a factor of . In this case, check and .

From the first equation,

and substituting into the second gives

4th option is correct xy=-10
