Question

simplify complex fractions:

Answer 1

\[x ^{-2}-9y ^{-2} \over 5y-15x\]

Answer 2

\[\frac{\frac{1}{x^2}-\frac{9}{y^2}}{5y-12x}\] is a start. then perhaps multiply top and bottom by \(x^2y^2\) to clear the fraction

Answer 3

thats 15 not12

Answer 4

you should get
\[\frac{y^2-9x^2}{x^2y^2(5y-15x)}\] then factor and cancel a bit

Answer 5

\[\frac{(y-3x)(y+3x)}{5x^2y^2(y-3x)}\] one step left

Answer 6

um cancel out y-3x

Answer 7

yes

Answer 8

thank you so much
