Question

2. Find the remainder whenx+3x+3x+1is divided
by X-1 by
without using long division method​

Answer 1

Step-by-step explanation:

By remainder theorem

x+1=0

x=−1

p(x)=x

3

+3x

2

−3x−1p(−1)

=(−1)

3

+3(−1)

2

−3(−1)−1

=−1+3(1)+3−1

=−1+3+3−1

=6−2

=4

Thus remainder is 4

Answer 2

Answer:

8

Explanation:

We can find the remainder by using remainder theorem.

Now,

x-1=0

x=1

So, p(x)= x+3x+3x+1

p(1)= 1+3*1+3*1+1 (replacing x with 1)

= 1+3+3+1

= 8
