Question

Find the remainder when x3

- 3x2 + x + 1 is divided by x – 1​

Answer 1

Answer:

I think answer is 5 or-1

Answer 2

Answer:

x+1=0

x=-1

p(x) = {x}^{3} + {3x}^{2} - 3x - 1p(x)=x

3

+3x

2

−3x−1

p( - 1) = {( - 1)}^{3} + 3 {( - 1)}^{2} - 3( - 1) - 1p(−1)=(−1)

3

+3(−1)

2

−3(−1)−1

= - 1 + 3(1) + 3 - 1=−1+3(1)+3−1

= - 1 + 3 + 3 - 1=−1+3+3−1

\begin{gathered}= 6 - 2 \\ \\ = 4\end{gathered}

=6−2

=4

Thus remainder is 4
