`(2sqrt3 + sqrt2)(2sqrt3-sqrt2)`

If a= (sqrt3 - sqrt2)/(sqrt3 + sqrt2), b = (sqrt3 + sqrt2)/(sqrt3 - sqrt2) then what is the value of a^2/b+b^2/a ?

The square root of ( (sqrt3 + sqrt2)/(sqrt3 - sqrt2)) is

(2sqrt3 + sqrt5)(2sqrt3 - sqrt5)

(2sqrt3+sqrt5)(2sqrt3+sqrt5)

[(sqrt3 + sqrt2 )/(sqrt3 - sqrt2) - (sqrt3 - sqrt2)/(sqrt3 + sqrt2)] simplifies to

If x= (sqrt3 - sqrt2)/(sqrt3+sqrt2) and y = (sqrt3+sqrt2)/(sqrt3-sqrt2) then x^2 +xy +y^2 is a multiple of

If a=(sqrt3+ sqrt2)/(sqrt3- sqrt2) and b=(sqrt3- sqrt2)/(sqrt3+sqrt2) , then what is the value of a^2+b^2-ab ?
