Combining Fractions
Posted:

Hello, I'm trying to solve a problem but I can't seem to get the answer correct.
The problem is: ((x+y)/(xy)) + (1/(x+y))  ((x^2+y^2)/(y^2x^2))
When I try to solve the problem, first thing I do is flip the sign of the last fractions numerator to flip the denominator so I can have a LCD.
((x+y)/(xy)) + (1/(x+y)) + ((x^2+y^2)/(x^2y^2))
Then I apply the LCD:
((x+y)(xy)) + x+y + (x^2+y^2)) / x^2y^2
Then simplify terms:
x^2y^2 + x+y + (x^2+y^2)) / x^2y^2
Then I eliminate the x^2y^2 from the equation:
x+y + (x^2+y^2)
I know this is grossly incorrect, I tried several different ways of solving this problem and I'm not even close. Any help will be appreciated.
