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!!!!
