Divide using synthetic division .
Dividend is .
Divisor is .
The divisor is in the form of .
where is the root.
Write the terms of the dividend such that the degrees of the terms are in descending order.
\Then write just the coefficients as shown below.
\
Write the constant of the divisor
to the left.
In this case, . Bring the first coefficient,
, down.
