Step-by-step Solution
Para resolver la expresión \( \frac{x^{2}-y^{2}}{x-y}+\frac{(x-y)^{2}}{x-y}-(x-y) \), comenzamos simplificando cada término.
1. **Simplificamos el primer término**:
\[
\frac{x^{2}-y^{2}}{x-y}
\]
Sabemos que \( x^{2}-y^{2} \) se puede factorizar como \( (x-y)(x+y) \). Por lo tanto:
\[
\frac{x^{2}-y^{2}}{x-y} = \frac{(x-y)(x+y)}{x-y} = x+y \quad \text{(ya que \( x \neq y \))}
\]
2. **Simplificamos el segundo término**:
\[
\frac{(x-y)^{2}}{x-y}
\]
Aquí, podemos simplificar directamente:
\[
\frac{(x-y)^{2}}{x-y} = x-y
\]
3. **Sustituyendo en la expresión original**:
Ahora sustituimos los resultados en la expresión original:
\[
x+y + (x-y) - (x-y)
\]
4. **Simplificamos la expresión**:
Observamos que \( (x-y) - (x-y) = 0 \), así que la expresión se reduce a:
\[
x+y + 0 = x+y
\]
Por lo tanto, el valor de la expresión es:
\[
\boxed{x+y}
\]
Quick Answer
El valor de la expresión es \( x+y \).
