Question

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

(i) How many students wrote cubic polynomial 

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

Answer 1

(i) 3 Students

(ii) x² +2x +1/x+1

= (x+1)/x+1 = x +1
