Question

10.1
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

Step-by-step explanation:

(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

(iv) Given polynomial h(y) = 2 y For zero of polynomial, put h(y) = 0

2y= 0

Hence, the zero of polynomial is

Answer 2

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

(iv) Given polynomial h(y) = 2 y For zero of polynomial, put h(y) = 0

2y= 0

Hence, the zero of polynomial is 0,
