Answer 1

Step-by-step explanation:

(ii) 3

21---1

Now 2r-1-1

= 21(1 - 1) + !!!

Hence, 2x + 3x - 3x - 2 = (x + 2) (x - 1) (2x + 1).

Exercise 6

S. If a

1. Find the remainder (without division) on

(1) f(x) = 5r2 - 7x + 4

(

(ii) f(x) = 32° + 722 - 5x

19. W

(1) f(x) = 2x2 - 5x + 1

(i) f(x) = 3x - 722 + 4x +11

20.

(1) f(x) = 4x2 + 5x + 3

leaves a remainder 7.

21

3+5r- ax + 6 by (x - 1) leaves the remainder 20

6.

leaves the remainder 2 when divided by 2x + 1?

(1) What number must be added to 22 - 7x + 2x so that the res

dividing f(x) by (x - 2) where

(ii) f(x) = 2x - 7x2 + 3.

2. Using remainder theorem, find the remainder on dividing f(x) by (x +3

3. Find the remainder (without division) on dividing f(x) by (2x + 1) where

4. Using remainder theorem, find the value of k if on dividing 22 + 3r--

5. Using remainder theorem, find the value of a if the division of
