Question 6

Find the quotient and remainder using synthetic division

( 2 x⁴ - 7 x³ -  13 x² + 63 x - 48 ) ÷ ( 2 x - 1 )

Solution

Let p (x) = 2 x⁴ - 7 x³ -  13 x² + 63 x - 48 be the dividend and q(x)=2x-1 be the divisor. We shall find the quotient s(x) and the remainder r, by proceeding as follows.

q (x) = 0

2 x - 1 = 0

2 x = 1

x = 1/2

Step 1:  Arrange the dividend and the divisor according to the descending powers of x and then write the coefficients of dividend in the first zero. Insert 0 for missing terms.

Step 2:  Find out the zero of the divisor.

Step 3:  Put 0 for the first entry in the second row.

Step 4:  Write down the quotient and remainder accordingly. All the entries except the last one  in the third row constitute the coefficients of the quotient.

When P (x) is divided by (2 x - 1), the quotient is 2 x³ - 6 x² - 16 x + 55 and the remainder is -41/2.

Quotient = 2 x³ - 6 x² - 16 x + 55

Remainder = -41/2
