Question

if x = √6+√5 then x^2+1/x^2-2 is equal to?​

Answer 1

Answer:

Step-by-step explanation:

so let's just consider x-1/x and square it we get

x²+1/x²-2 which is the question so what we need actually is (x-1/x)²

plugging in the value of x we get (√6+√5)²-1)²/(√6+√5)² so we get

(10+2√30)/(11+2√30) is the answer
