Question

can anyone help to solve this... which is the correct option and explain ​

Answer 1

Answer:

(i)

Step-by-step explanation:

The easiest way to answer on this question, without long division, is to "plug-in" (- 1) into each polynomial and find out which one give us 0.

(-1) is zero for (x + 1) and for whole polynomial as well.

(i) - 1 + 1 - 1 + 1 = 0

(ii) 1 - 1+ 1 - 1 + 1 = 1

(iii) 1 - 3 + 3 - 1 + 1 = 1
