To find the quotient when
2x^3+x+3 is divided by
x+1 you have to do such steps:

1. Multiply
x+1 by
2x^2 and subtract the result from the
2x^3+x+3 in order to eliminate
2x^3 term:


2x^3+x+3-2x^2(x+1)=2x^3+x+3-2x^2-2x^2=-2x^2+x+3.

2. Multiply
x+1 by
-2x and subtract the result from the
-2x^2+x+3 in order to eliminate
-2x^2 term:


-2x^2+x+3-(-2x)(x+1)=-2x^2+x+3+2x^2+2x=3x+3.

3. Multiply
x+1 by
3 and subtract the result from the
3x+3 in order to eliminate
3x term:


3x+3-3(x+1)=3x+3-3x-3=0.

4. Now you can write that


2x^3+x+3=(x+1)(2x^2-2x+3).

The quotient is
2x^2-2x+3 and the remainder is 0.

Answer: correct choice is B
