Q. Use synthetic division to find (x2−18x+17)÷(x−1).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 1 as the zero from (x−1) and the coefficients of the polynomial x2−18x+17 as 1, −18, and 17.
Bring down leading coefficient: Bring down the leading coefficient (1) to the bottom row.
Multiply zero by number: Multiply the zero (0) by the number just brought down (1) and write the result (0) under the next coefficient (−18).
Add numbers in second column: Add the numbers in the second column (−18+1=−17) and write the result (−17) in the bottom row.
Multiply zero by new number: Multiply the zero (1) by the new number in the bottom row (−17) and write the result (−17) under the next coefficient (17).
Add numbers in third column: Add the numbers in the third column 17+(−17)=0 and write the result 0 in the bottom row.
Identify quotient polynomial: The numbers in the bottom row are the coefficients of the quotient polynomial q(x), and the last number is the remainder r. So, q(x)=x−17 and r=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 q(x).
