**If a + 1/a = p and a – 1/a = q, Find the relation between p and q.**

**Answer :**

It is given that,

a + 1/a = p and a – 1/a = q

so,

(a + 1/a)^{2} – (a – 1/a)^{2} = 4(a) (1/a)

= 4

By substituting the values, we get

p^{2} – q^{2} = 4

Hence the relation between p and q is that p^{2} – q^{2} = 4.
