Question

Karine preformed the polynomial division shown below.

(x^4+3x^2-x-8)/ (x+3)

| 1 3 0 -1 -8

3 | 3 18 54 159

|

_________________________

1 6 18 53 151

x^3+6x^2+18x+204

1)Explain the errors in detail.

2)Enter the correct synthetic division below showing the entire process and answer in polynomial form.

Answer 1

-3 | 1 0 3 -1 -8

-3 9 -36 111

--------------------------

1 -3 12 -37 103

x^3 - 3x^2 + 12x - 37 +103/x+3

Answer 2

The coefficients of the dividend are not in correct order.

They should be 1 0 3 -1 -8

In synthetic division the partial products are subtracted, not added.
