Problem 25
If and are the quotient and remainder, respectively, when the polynomial is divided by , and if and are the quotient and remainder, respectively, when is divided by , then equals
Solution
Solution by e_power_pi_times_i
First, we divide by using synthetic division or some other method. The quotient is , and the remainder is . Then we plug the solution to into the quotient to find the remainder. Notice that every term in the quotient, when , evaluates to . Thus .
