Question

the remainder f(x)=x³-2x²+3x+1 is divide by 2x + 1​

Answer 1

Step-by-step explanation:

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

Step-by-step explanation:

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

let p(x)=x3−2x2+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)=13−2×12+1+1

p(1)=1
