also an integer?​

Answer 1

Step-by-step explanation:

this is your answer

Mark as brain list.

Answer 2

01  Integer value of n so that your question is an integer.

Given:

equation -  (2n^2+1)/(n^2-1)

To Find:

how many integers n is the fraction $2n^{2} +1 / n^{2} -1$

also an integer

$2n^{2} +1 / n^{2} -1$

case -01 :

n = 0,

$2(0)^{2} +1 / (0)^{2} -1$

=   - 1

case -02 :

n = 1,

$2(1)^{2} +1 / (1)^{2} -1$

=  not defined.

so,

"0"  is the value that satisfies this equation correctly.

Hence answer is [ One ] 1  interger.
