(iv) We have p(x) = 3x - 2
∴ p(x) = 0
⇒ 3x - 2 = 0
⇒ 3x = 2
2
⇒ x =
3
2
Thus, a zero of 3x – 2 is
3
(v) Since p(x) = 3x
∴ p(x) = 0
⇒ 3x = 0

Thus, a zero of 3x is 0.
(vi) Since, p(x) = ax, a ≠ 0
∴ p(x) = 0
⇒ ax = 0
0
⇒ x = = 0

Thus, a zero of ax is 0.
(vii) Since, p(x) = cx + d
∴ p(x) = 0
⇒ cx + d = 0
⇒ cx = –d
⇒ x = − = 0

Thus, a zero of cx + d is − .
