Step-by-step explanation:
- [tex] \cfrac{(9y²-x² )}{ (xy+3y²)}[/tex]
- [tex] \cfrac{3 {}^{2} (y) {}^{2} - x}{3(y {})^{2} + xy } [/tex]
- [tex]3 {}^{2 - 1} y {}^{2 - 2 - 1} - x {}^{2 - 1} [/tex]
- [tex]3 y { }^{ - 1} - x[/tex]
- [tex] \cfrac{3}{y} - x[/tex]
Therefore,the answer is [tex] \cfrac{3}{y} - x[/tex].
