Q26 of 40 Page 1

Read the following passage and answer the questions that follows:

A teacher told 10 students to write a polynomial on the black board.


Students wrote


1. x2 + 2


2. 2x + 3


3. x3 + x2 + 1


4. x3 + 2x2 + 1


5. x2 – 2x + 1


6. x – 3


7. x4 + x2 + 1


8. x2 + 2x + 1


9. 2x3 – x2


10. x4 – 1


(i) How many students wrote cubic polynomial


(ii) Divide the polynomial (x2 + 2x + 1) by (x + 1)


(i) Cubic polynomials are polynomials with a degree of 3. So, from the data given, only 3 polynomials have a maximum degree of 3. Thus, the answer is 3.


(ii) To divide (x2 + 2x + 1) by (x + 1)
