Answer:
Option (2)
Step-by-step explanation:
Given :-
P(x +1/x) = x^2 + 1/ x^2
To find:
If P(x +1/x) = x^2 + 1/ x^2 then find the value of P(x) ?
Solution:-
Given that P(x +1/x) = x^2 + 1/ x^2
we know that (a + 1/a)^2 = a^2+1/a^2 +2
=>a^2 + 1/a^2 = (a + 1/a)^2 -2
P(x + 1/x) = (x + 1/x )^2 -2
Let Y= x + 1/x then
=>P(Y) = Y^2-2
On replacing y by X then
=>P(X)=X^2 - 2
Answer:-
The value of P(X) is equal to X^2 - 2
Used formula:-
