Answer 2

Answer:

7

Step-by-step explanation:

The division algorithm is used here.

P(x) = g(x)Q(x) + R(x)

The goal is to make g(x)Q(x) turn into 0, then it will vanish.

Since we know g(x)=x+1, we apply x+1=0

Then, P(-1)=R(-1).

We can observe, that we have to apply x=-1 on given polynomial.

P(-1) = 1 - 1 + 1 + 5 + 1 = 7, therefore, remainder is 7.
