EXERCISE 2.2

(i) Can be the quotient on division of by a polynomial in x of degree 5?

(ii) What will the quotient and remainder be on division of by , ?

(iii) If on division of a polynomial by a polynomial , the quotient is zero, what is the relation between the degrees of and ?

(iv) If on division of a non-zero polynomial by a polynomial , the remainder is zero, what is the relation between the degrees of and ?

(v) Can the quadratic polynomial has equal zeroes for some odd integer ?

(i) If the zeroes of a quadratic polynomial are both positive, then a, b and c all have the same sign.

(ii) If the graph of a polynomial intersects the x-axis at only one point, it cannot be a quadratic polynomial.

(iii) If the graph of a polynomial intersects the x-axis at exactly two points, it need not be a quadratic polynomial.

(iv) If two of the zeroes of a cubic polynomial are zero, then it does not have linear and constant terms.

(v) If all the zeroes of a cubic polynomial are negative, then all the coefficients and the constant term of the polynomial have the same sign.
