(i) p(x) = x – 4

For the zero of the polynomial p(x) we put p(x) = 0

⇒ x – 4= 0 ⇒ x = 4

Hence the zero of the polynomial is 4.

(ii) g(x) = 3 – 6x

For the zero of the polynomial Putting g(x) = 0 we get

3 – 6x = 0 ⇒ x = 3/6 = 1/2

Hence the zero of the polynomial is 1/2

(iii) q(x) = 2x –7

For the zero of the polynomial Putting q(x) = 0 we get

2x – 7 = 0 ⇒ x = 7/2

Hence the zero of the polynomial is 7/2

(iv) h (y) = 2y

For the zero of the polynomial Putting h(y)= 0 we get

2y =0 ⇒ y = 0

Hence the zero of the polynomial is 0
