Question

need help, can't get the right answer
complex fraction
2x^-2 + y^-2/x^-1 - y^-1

Answer 1

Is this the question?

\[\frac{2x^{-2} + y^{-2}}{x^{-1} - y^{-1}}\]

Answer 2

yes that's it

Answer 3

\[\{2x{}^{\wedge}-2+y{}^{\wedge}-2\}/(x{}^{\wedge}-1-y{}^{\wedge}-1)=\frac{\frac{2}{x^2}+\frac{1}{y^2}}{\frac{1}{x}-\frac{1}{y}}=\frac{3}{y-x}+\frac{2}{x}-\frac{1}{y} \]

Answer 4

the first part is right, thanks, i got it
