p ?, p+q 1 is answer ok I am teacher ok

Answer 2

Answer:

$\boxed{\mathrm {pq = 1}}$ is the correct option

Step-by-step explanation:

Given,

$x + \frac{1}{x} = p+q \texttt{ -----(1) } \\\\and \ x - \frac{1}{x} = p-q \texttt{ -----(2)}$

Now, adding (1) and (2), we get,

2x = 2p

x = p -----(3)

Now, subtracting (1) and (2),

$\frac{2}{x} = 2q$

$\frac{1}{x} = q \\\\x = \frac{1}{q} \texttt{ ----- (4)}$

As, (3) and (4) are equal to x

p = 1/q

=> pq = 1
