Aditya determines the remainder of −12x^17+3x^5−9x^2−1/x+1 , using the remainder theorem.

How does he proceed to the correct answer?

Aditya evaluates the numerator of the expression when x = 1. He finds the remainder of the division to be −1 .

Aditya evaluates the numerator of the expression when x = 1. He finds the remainder of the division to be −19 .

Aditya evaluates the numerator of the expression when x=−1 . He finds the remainder of the division to be −19 .

Aditya evaluates the numerator of the expression when x=−1 . He finds the remainder of the division to be −1 .

First one....we are testing whether x + 1 is a divisor of the numerator.....this is the same as testing whether -1 is a root....so.....

Sub -1 into the the numerato and we get that

−12(-1)^17+3(-1)^5−9(-1)^2−1 =

12 - 3 - 9 - 1 =

-1

Aditya evaluates the numerator of the expression when x=−1 . He finds the remainder of the division to be −1 .

You are correct, Jenny!!!!
