*⃣ STEP-BY-STEP EXPLANATION *⃣
==================================
⏩ First of all we had used the formula of a²-b² which is equal to (a+b)²-2ab
⏩ After proceeding, we hold (x + 1/x) as "a".
⏩ After holding it as "a", we again proceeded forward.
⏩ We factorised the expression "2a²-3a-5".
⏩ We get : (2a-5) (a+1) = 0.
⏩ We took the main one, i.e., 2a-5 = 0.
⏩ We put the value of "a" in its place.
⏩ Again we have to proceed our steps by means of factorisation.
⏩ A final answer is ultimately obtained.
