Question

Find the sum.
1
x2
-
xy2
y

Answer 1

`(1)/(xy^2)+(x^2)/(y)`

`(1)/(xy^2)+(x^3y)/(xy^2)`

`(1+x^3y)/(xy^2)`

Answer 2

`= \frac{1 + {x}^(3) y}{x {y}^(2) } \\`

Explanation:

`\frac{1}{x {y}^(2) } + \frac{ {x}^(2) }{y} \\ \frac{1}{x {y}^(2) } + \frac{ {x}^(3) y}{x {y}^(2) } \\ = \frac{1 + {x}^(3) y}{x {y}^(2) }`
