Q. Use synthetic division to find (x2−9x+14)÷(x−2).Write your answer in the form q(x)+d(x)r, where q(x) is a polynomial, r is an integer, and d(x) is a linear polynomial. Simplify any fractions._________
Set up synthetic division: Set up synthetic division with 2 as the root from (x−2) and the coefficients of the polynomial x2−9x+14 as 1, −9, and 14.
Bring down leading coefficient: Bring down the leading coefficient (1) to the bottom row.
Multiply root by number: Multiply the root (2) by the number just brought down (1) and write the result (2) under the next coefficient (−9).
Add numbers in column: Add the numbers in the second column (−9+2=−7) and write the result (−7) in the bottom row.
Multiply root by new number: Multiply the root (2) by the new number in the bottom row (−7) and write the result (−14) under the next coefficient (14).
Add numbers in column: Add the numbers in the third column 14+(−14)=0 and write the result 0 in the bottom row.
Identify quotient and remainder: The numbers in the bottom row represent the coefficients of the quotient polynomial q(x) and the remainder r. The quotient polynomial is x−7 and the remainder is 0.
Write final answer: Write the final answer in the form q(x)+d(x)r. Since the remainder is 0, the division is exact and the result is just the quotient polynomial q(x).
