To use synthetic division to divide
, we first need to rewrite the divisor
in the form
. We can do this by setting
, which gives us
. So, we will use
for synthetic division.The coefficients of the polynomial
are
.Now, we set up the synthetic division:
Here's the step-by-step process:1. Bring down the first coefficient (1).2. Multiply -9 by the value just written below the line (1), which gives -9. Write this under the next coefficient (5).3. Add the values in the second column: \(5 + (-9) = -4\). Write this result below the line.4. Multiply -9 by the value just written below the line (-4), which gives 36. Write this under the next coefficient (-36).5. Add the values in the third column:
. Write this result below the line.The final row gives us the coefficients of the quotient polynomial. Since the remainder is 0, the quotient polynomial is
.Therefore,
.
