Q. Use synthetic division to find (5x2−14x+27)÷(x−3).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 the root of the divisor, which is 3, and the coefficients of the dividend, which are 5, −14, and 27.
Bring down leading coefficient: Bring down the leading coefficient, which is 5.
Multiply root by coefficient: Multiply the root by the leading coefficient we just brought down, which is 3×5=15, and write this number under the second coefficient, −14.
Add numbers in second column: Add the numbers in the second column, −14+15=1, and write this number below the line.
Multiply root by new number: Multiply the root by the new number we just got, which is 3×1=3, and write this number under the third coefficient, 27.
Add numbers in third column: Add the numbers in the third column, 27+3=30, and write this number below the line.
Write result of synthetic division: Write the result of synthetic division in the form q(x)+d(x)r, where q(x) is the quotient polynomial and r is the remainder. The coefficients from the synthetic division give us q(x)=5x+1 and the remainder is 30.
