To use synthetic division to divide , we first need to rewrite the divisor in the form . In this case, .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 -5 by the value just written below the line (1), which gives -5. Write this under the next coefficient (14).3. Add the values in the second column: \(14 + (-5) = 9\).4. Multiply -5 by the new value (9), which gives -45. Write this under the next coefficient (8).5. Add the values in the third column: \(8 + (-45) = -37\).6. Multiply -5 by the new value (-37), which gives 185. Write this under the next coefficient (-9).7. Add the values in the fourth column: .The final row gives the coefficients of the quotient polynomial and the remainder. The quotient polynomial is and the remainder is 176.So, the result of the division is: In simplified form, without factoring the remainder, the answer is:
