Question

4. Find the zero of the polynomial in each of the following cases.
(1) f(x) = x + 2 (ii) f(x) = x - 2 (ii) f(x) = 2x + 3
(iv) (x) = 2x – 3 (v) (x) = 2 (vi) f(x) = px, p = 0
(vi) f(x) = px +q, p = 0, p q are real numbers.
5. If 2 is a zero of the polynomial p(x) = 2x2 – 3x + 7a, find the value of a.
6. If 0 and 1 are the zeroes of the polynomial f(x) = 2x -3x+ + ax + b, find the values
of a and b.
