Step-by-step Solution

Para simplificar la expresión \( \frac{x^{2}-3x}{x^{2}+3x} \), primero factorizamos tanto el numerador como el denominador. 1. **Numerador**: \( x^{2} - 3x \) se puede factorizar como: \[ x(x - 3) \] 2. **Denominador**: \( x^{2} + 3x \) se puede factorizar como: \[ x(x + 3) \] Ahora, reescribimos la fracción con las factorizaciones: \[ \frac{x(x - 3)}{x(x + 3)} \] Observamos que \( x \) se encuentra en el numerador y en el denominador, así que podemos cancelarlo, siempre y cuando \( x \neq 0 \): \[ \frac{x - 3}{x + 3} \] Por lo tanto, la expresión simplificada es: \[ \frac{x - 3}{x + 3}, \quad \text{con } x \neq 0 \]

Quick Answer

La expresión simplificada es \( \frac{x - 3}{x + 3} \), siempre y cuando \( x \neq 0 \).
