Question 2:

Check whether the first polynomial is a factor of the second polynomial by dividing the second polynomial by the first polynomial.

(i) (ii) (iii)

(i)

Remainder Hence first polynomial is a factor of second polynomial. (ii)

Remainder Hence first polynomial is a factor of second polynomial. (iii)

Remainder

Hence first polynomial is not factor of second polynomial.

Question 3:

Obtain all other zeroes of , if two of its zeroes are and - .

Two zeroes of are and which means that is a factor of .

Applying Division Algorithm to find more factors we get:

We have .

Therefore, other two zeroes of are and .

Question 4:

On dividing by a polynomial , the quotient and remainder were and respectively. Find .
