Question

Simplify (9y²-x² )÷ (xy+3y²)

Answer 1

Step-by-step explanation:

• $\cfrac{(9y²-x² )}{ (xy+3y²)}$
• $\cfrac{3 {}^{2} (y) {}^{2} - x}{3(y {})^{2} + xy }$
• $3 {}^{2 - 1} y {}^{2 - 2 - 1} - x {}^{2 - 1}$
• $3 y { }^{ - 1} - x$

• $\cfrac{3}{y} - x$

Therefore,the answer is $\cfrac{3}{y} - x$.
