Find Quotient and Remainder Using Synthetic Division :

Here we are going to see some practice questions to understand the concept of finding quotient and remainder using synthetic division.

## Find Quotient and Remainder Using Synthetic Division - Practice questions

Question 1 :

Find the quotient and remainder for the following using synthetic division:

(i)  (x3 + x2 - 7x - 3) ÷ (x - 3)

Solution :

Quotient  =  x2 + 4x - 3

Remainder  =  -12

(ii)  (x3 + 2x2 - x - 4) ÷ (x + 2)

Solution :

Quotient  =  x2 + 0x - 1

Remainder  =  -2

(iii)  (3x3 - 2x2 + 7x - 5) ÷ (x + 3)

Solution :

Quotient  =  3x2 - 11x + 40

Remainder  =  -125

(iv)  (8x4 - 2x2 + 6x + 5) ÷ (4x + 1)

Solution :

Quotient  =  8x2 - x + 40

Remainder  =  -125

(iv)  (8x4 - 2x2 + 6x + 5) ÷ (4x + 1)

Solution :

Quotient : 8x3 - 2x2 -(3x/2) + (51/8)

Remainder  : 109/32

Question 2 :

If the quotient obtained on dividing (8x4 - 2x2 + 6x - 7) by (2x + 1) is (4x3 + px2 - qx + 3) then find p, q and also the remainder.

Solution :

8x3 - 4x2 + 0x + 6

Dividing the quotient by 2, we get

4x3 - 2x2 + 0x + 3

The value of p and q are -2 and 0 respectively and remainder is -10.

Question 3 :

If the quotient obtained on dividing 3x3 + 11x2 + 34x + 106 by x - 3 is 3x2 + ax + b, then find a, b and also the remainder.

Solution :

Quotient  =  3x2 + 20x + 94

Given quotient  =  3x2 + ax + b

a  =  20 and b  =  94.
