The Deep Dive

Para resolver la ecuación \( x^{2}+9x+14=0 \) por factorización, buscamos dos números que se multiplican para dar 14 (el término constante) y que suman 9 (el coeficiente del término lineal). Los números que cumplen esta condición son 7 y 2. Por lo tanto, podemos factorizar la ecuación como: \((x + 7)(x + 2) = 0\) Ahora, aplicando la propiedad del producto cero, establecemos las ecuaciones: \(x + 7 = 0\) y \(x + 2 = 0\) De aquí, despejamos \(x\) y obtenemos: \(x = -7\) y \(x = -2\). ¡Y ahí tenemos las soluciones!
