Now set up the synthetic division table by placing the test zero in the upper left corner and placing the coefficients of the numerator to the right of the test zero.

Start by bringing down the leading coefficient (it is the coefficient with the highest exponent which is 1)

Multiply -3 by 1 and place the product (which is -3) right underneath the second coefficient (which is -5)

Add -3 and -5 to get -8. Place the sum right underneath -3.

Multiply -3 by -8 and place the product (which is 24) right underneath the third coefficient (which is -2)

Since the last column adds to 22, we have a remainder of 22. This means is not a factor of
Now lets look at the bottom row of coefficients:
The first 2 coefficients (1,-8) form the quotient
and the last coefficient 22, is the remainder, which is placed over like this
Putting this altogether, we get:
So
which looks like this in remainder form:
remainder 22
