 Remainder


Answer:_______________




 

1)  

 Find the remainder using remainder theorem, when 

5x4+10x3 + 2x2 - 6x + 6 is divided by x - 1 

 Remainder Answer: 13


SOLUTION 1 :

 5x4+10x3 - 2x- 6x + 6 is divided by x - 1 

When P(x) is divided by x - 1, the remainder is P(1)

p(1) = 5(1)4 + 10(1)3 - 2(1)2 - 6(1) + 6

=5 + 10 - 2 - 6 + 6

= 13

Remainder = 13



2)  

 Find the remainder using remainder theorem, when 

4x3 + 7x2 - 2x + 3 is divided by x- 3 

 Remainder Answer: 168


SOLUTION 1 :

 4x3 + 7x- 2x + 3 is divided by x - 3 

When P(x) is divided by x - 3, the remainder is P(3)

p(3) = 4(3)3 + 7(3)2 - 2(3) + 3

= 4(27) + 7(9) - 2(3) + 3

= 108 + 63 - 6 + 3

= 168

Remainder = 168



3)  

 Find the remainder using remainder theorem, when 

x3 - Ix2 - 8x + 3I is divided by x- I 


 Remainder Answer: 5


SOLUTION 1 :

 x3 - Ix- 8x + 3I is divided by x- I 

I3 - I(I)2 - 8(I) + 3I

I3 - I3 - 8I + 3I

= - 8I + 3I

Remainder = -5


4)  

 Find the remainder using remainder theorem, when 

7x4+11x3 + 7x2 - 9x + 4 is divided by x - 1 

 Remainder Answer: 6


SOLUTION 1 :

 7x4+11x3 - 7x- 9x + 4 is divided by x - 1 

When P(x) is divided by x - 1, the remainder is P(1)

p(1) = 7(1)4 + 11(1)3 - 7(1)2 - 9(1) + 4

=7 + 11 - 7 - 9 + 4

= 6

Remainder = 6



5)  

 Find the remainder using remainder theorem, when 

5x3 + 8x2 - 9x + 3 is divided by x- 1 

 Remainder Answer: 7


SOLUTION 1 :

 5x3 + 8x- 9x + 3 is divided by x - 1 

When P(x) is divided by x - 1, the remainder is P(1)

p(1) = 5(1)3 + 8(1)2 - 9(1) + 3

= 5(1) + 8(1) - 9(1) + 3

= 5 + 8 - 9 + 3

= 7

Remainder = 7



6)  

 Find the remainder using remainder theorem, when 

x3 - Yx2 - 15x + 3Y is divided by x- Y 


 Remainder Answer: 12


SOLUTION 1 :

 x3 - Yx- 15x + 3Y is divided by x- Y 

Y3 - Y(Y)2 - 15(Y) + 3Y

Y3 - Y3 - 15Y + 3Y

= - 15Y + 3Y

Remainder = -12


7)  

 Find the remainder using remainder theorem, when 

5x4+13x3 + 3x2 - 8x + 6 is divided by x - 1 

 Remainder Answer: 13


SOLUTION 1 :

 5x4+13x3 - 3x- 8x + 6 is divided by x - 1 

When P(x) is divided by x - 1, the remainder is P(1)

p(1) = 5(1)4 + 13(1)3 - 3(1)2 - 8(1) + 6

=5 + 13 - 3 - 8 + 6

= 13

Remainder = 13



8)  

 Find the remainder using remainder theorem, when 

8x3 + 6x2 - 3x + 2 is divided by x- 3 

 Remainder Answer: 263


SOLUTION 1 :

 8x3 + 6x- 3x + 2 is divided by x - 3 

When P(x) is divided by x - 3, the remainder is P(3)

p(3) = 8(3)3 + 6(3)2 - 3(3) + 2

= 8(27) + 6(9) - 3(3) + 2

= 216 + 54 - 9 + 2

= 263

Remainder = 263



9)  

 Find the remainder using remainder theorem, when 

x3 - Jx2 - 9x + 6J is divided by x- J 


 Remainder Answer: 3


SOLUTION 1 :

 x3 - Jx- 9x + 6J is divided by x- J 

J3 - J(J)2 - 9(J) + 6J

J3 - J3 - 9J + 6J

= - 9J + 6J

Remainder = -3


10)  

 Find the remainder using remainder theorem, when 

4x4+11x3 + 5x2 - 2x + 11 is divided by x - 1 

 Remainder Answer: 19


SOLUTION 1 :

 4x4+11x3 - 5x- 2x + 11 is divided by x - 1 

When P(x) is divided by x - 1, the remainder is P(1)

p(1) = 4(1)4 + 11(1)3 - 5(1)2 - 2(1) + 11

=4 + 11 - 5 - 2 + 11

= 19

Remainder = 19
