Question

How do you divide `(2x^4-3x^3+x^2-11)div(x+3)` using synthetic division?

Answer 1

`Q(x)=2x^3-9x^2+28x-84`
`R=241`

Explanation:

Ruffini scheme:
first row I get coefficients,
second row on the left the known term with changed sign (-3) and
I get results of sums in columns and products by -3
third row: I get result's coefficients
