Answer:

Step-by-step explanation:

a.

x^3 - x^2 - 2x + 0 divided by x + 1

x + 1 = 0

x = -1

The number to the left inside the box should be -1, not 1.

The coefficients of the dividend are: 1, -1, -2, and 0. The zero is missing.

-1    |   1     -1    -2   0

               -1     2   0

          1    -2     0   0

The coefficients of the answer are 1, -2, and 0. The quotient is 1 degree lower than the dividend, so the quotient is x^2 - 2x. The remainder is 0.

b.

f(x) = x^3 - x^2 - 2x

f(0) = 0^3 - 0^2 - 2(0) = 0
