Question

Using remainder theorem, find the remainder when 3x³- 2x² +x 1 is divided by x +1.​

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

Answer 2

Answer:
