To simplify the expression \( \frac{2y^2 - 2xy}{x^2 - y^2} \), we can factor both the numerator and the denominator.

Step 1: Factor the numerator

The numerator \( 2y^2 - 2xy \) can be factored as:

\[ 2y(y - x) \]

Step 2: Factor the denominator

The denominator \( x^2 - y^2 \) can be factored using the difference of squares:

\[ x^2 - y^2 = (x - y)(x + y) \]

Step 3: Rewrite the expression

Now, we rewrite the expression with the factored numerator and denominator:

\[ \frac{2y(y - x)}{(x - y)(x + y)} \]

Step 4: Simplify the expression

Notice that \( y - x \) can be rewritten as \( -(x - y) \):

\[ \frac{2y(y - x)}{(x - y)(x + y)} = \frac{2y(-1)(x - y)}{(x - y)(x + y)} \]

We can now cancel \( (x - y) \) from the numerator and denominator (assuming \( x \neq y \)):

\[ \frac{-2y}{x + y} \]

So, the simplest form of the expression is:

\[ \frac{-2y}{x + y} \]

Final Answer:

Start Fraction negative 2 y over x plus y End Fraction
