Question

5x3 + 6x + 8 by x + 2
use synthetic division

Answer 1

Hi tjdenerson :)

Welcome again :)

Answer 2

hey

Answer 3

First we have to separate coefficients of the polynomial like this.
\[\large 5x^3+0x^2+6x+8\]
separate coeffiecients
\[\large 5 \space0\space6\space\text{and}\space8\]

As you can see x^2 term in the question was missing. So I have added it with 0 coefficient. Right?

Answer 4

Now as we have given x+2 as a factor to divide with
So
x+2=0
from here
x=-2

Now we have -2 by which we will divide.

Answer 5

that wasnt one of my choices did u use synthetic dicicion

Answer 6

Yes I am using synthetic division. In this division we have to divide with coefficients of polynimial not with the actual polynomial.

Answer 7

oh ....thanks beautiful

Answer 8

So should I continue?

Answer 9

yeah
