Question

0. Find the zeroes of the polynomial in each of the following,
(i) p(x)= x – 4
(ii) g(x)= 3 – 6x
(iii) q(x) = 2x – 7

Answer 1

Answer:

(i) Given, polynomial is

p(x) = x- 4

For zero of polynomial, put p(x) = x-4 = 0

⇒ x= 4

Hence, zero of polynomial is 4.

(ii) Given, polynomial is

g(x) = 3-6x

For zero of polynomial, put g(x) = 0

3 - 6x = 0 ⇒ 6x =3 ⇒ x=1/2.

Hence, zero of polynomial is X

(iii) Given, polynomial is q(x) = 2x -7 For zero of polynomial, put q(x) = 2x-7 = 0

2x= 7 ⇒ x =7/2

Hence, zero of polynomial is

Answer 2

Answer:

(i) p(x)= x – 4

the zeroes of the polynomial is 4

(ii) g(x)= 3 – 6x

the zeroes of the polynomial is 1/2

(iii) q(x) = 2x – 7

the zeroes of the polynomial is 7/2
