Question

find the remainder when 3×2+x-1 is divided by (x+1). please fast​

Answer 1

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
