Question

find remainder when (x³—2x²—x+1) is divided by x+2 remainder theorem​

Answer 1

Answer:

For finding the remainder, we need to use remainder theorem.

let p(x)=x  

3

−2x  

2

+x+1

Hence, to find the remainder on dividing by x−1, we need to equate it to 0 and put that value of x in p(x).

⇒x−1=0

⇒x=1

p(1)=1  

3

−2×1  

2

+1+1

p(1)=1
