simplify 1/2xy - 1/x^2+y^2
simplify 1/2xy - 1/x^2+y^2
simplify 1/2xy - 1/x^2+y^2
Solution
1/2xy -1/(x^2+y^2)
the LCD is (x^2+y^2)*2xy
=> make the denominator in both the terms the same as the LCD
=> (x^2+y^2)/[(x^2+y^2)*2xy] - 2xy/[(x^2+y^2)*2xy]
now add the terms in the numerator
=>[x^2 + y^2 - 2xy]/[(x^2+y^2)*2xy]
using the identity (a-b)^2 = a^2 -2ab +b^2 in the numerator
=> (x - y)^2/[(x^2+y^2)*2xy] -------> this is the simplified expression
