(5x^-2)-(3y^-1) --------------- (x^-1)+(y^-1)

(1) ------------- 25x^2 + 22xy - 3y

I get (5x^-1)-3!

I do not understand how you arrived @ this answer. Can you please explain. Thank you

sure! :) remember that we can add/subtract exponents just like normal numbers. First put everything in the numerator and then add up all the exponents. (5x^-2)-(3y^-1) --------------- (x^-1)+(y^-1) (5x^-2)+(x^1)-(3y^-1)+(y^1) now add: (5x^-1)-3 x^=-2+1=-1 y^=-1+1=0 or goes away Does this help?

There is no division here? Is this all adding and subtracting?

I thought there was division too. So what is the final answer?

you can do it by division or add/subtract. I did it by add/substract because its easier. First you put all the terms in the numerator. Then you combine terms and add/substract exponents to get your answer. Follow the steps above and you will see the answer. Do you get it now?
