Question

exercise 2.2 chapter 2 maths class 9th. third and fourth ques​

Answer 1

Answer:

I will give your answer

Step-by-step explanation:

4.i).

4.i). p(x)=x+5

If p(x) = 0. then,

p(x)= x+5= 0

x= 0-5= -5

-5 is the zero of p(x)

ii).

p(x) = 0

x-5= 0

x=5

So,x=5 is a zero of the given polynomial.

iii).

p(x) = 0

2x + 5 = 0

2x = -5

x= -5/2

So,x=-5/2 is a zero of the given polynomial.

iv).

p(x)= 0

3x-2= 0

3x = 2

x= 2/3

So, x= 2/3 is zero of polynomial.

v).

p(x) = 0

3x = 0

x = 0/3

x= 0

So,x= 0 is a zero of polynomial

vi).

p(x) = 0

ax= 0

x= 0/a

x= 0

So,x= 0 is a zero of the given polynomial.

vii).

p(x) = 0

cx+d= 0

cx= -d

x= -d/c

So,x = -d/c is a zero of the given polynomial.

Hope this helps you.
