Question

A: x²-4 एक रैखिक समीकरण है। R: 2 बहुपद x²-4 का एक शुन्यक है। ​

Answer 1

I dont know how to write  but the answer is  x + 2 ,

Answer 2

Given : A: x²-4 एक रैखिक समीकरण है।

R: 2 बहुपद x²-4 का एक शुन्यक है। ​

A - Assertion

R - Reasoning

To Find : Both A and R are true and R is correct explanation of A

Both A and R are true and R is not correct explanation of A

A is true but R is False

A is False but R is True.

Both A and R are false.

Solution:

A: x²-4 एक रैखिक समीकरण है।

FALSE

रैखिक समीकरण  Ax + By +  C = 0   where A and B  , both can not be 0

Here power of x is 2

Hence its Quadratic not linear

=>  x²-4 एक रैखिक समीकरण है। is FALSE

R: 2 बहुपद x²-4 का एक शुन्यक है। ​

x²-4 = 0

=> (x + 2)(x - 2) = 0

=>  x= -2  or  x = 2

Hence  2 बहुपद x²-4 का एक शुन्यक है।

R: 2 बहुपद x²-4 का एक शुन्यक है। ​  TRUE

A is FALSE , R is TRUE
