Question

(х/у^2 - 1/х) : (1/у^2 -1/х^2) СРОЧНО!!!

Answer 1

1)х/у^2-1/х=х^2-у^2/х*у^2
2)1/ у+1/х=х+у/у*х

Answer 2

Simplifying the Expression

To simplify the given expression (x/y^2) + (1/y^2 - 1/x^2), we can follow the steps below:

1. Common Denominator: Find the common denominator for the fractions. 2. Combine the Fractions: Combine the fractions using the common denominator. 3. Simplify the Result: Simplify the combined expression.

Let's proceed with the steps to simplify the given expression.

Step 1: Find the Common Denominator

The common denominator for the fractions x/y^2 and 1/y^2 - 1/x^2 is x^2y^2.

Step 2: Combine the Fractions

Combining the fractions using the common denominator, we get: ((x^2 - y^2) + (y^2 - x^2)) / (x^2y^2)

Step 3: Simplify the Result

Simplifying the combined expression, we get: 0 / (x^2y^2)

Therefore, the simplified form of the given expression (x/y^2) + (1/y^2 - 1/x^2) is 0 / (x^2y^2).

I hope this helps! If you have further questions or need additional assistance, feel free to ask.
