Primero, reordenemos la ecuación para que todos los términos estén en un solo lado: \[ 3w^{2} + 7w - 6 = 0 \] Ahora, aplicamos la fórmula cuadrática \( w = \frac{-b \pm \sqrt{b^{2} - 4ac}}{2a} \), donde \( a = 3 \), \( b = 7 \), y \( c = -6 \). Calculamos el discriminante: \[ b^{2} - 4ac = 7^{2} - 4 \cdot 3 \cdot (-6) = 49 + 72 = 121 \] Como el discriminante es positivo, hay dos soluciones. Ahora, usamos la fórmula: \[ w = \frac{-7 \pm \sqrt{121}}{2 \cdot 3} = \frac{-7 \pm 11}{6} \] Calculamos las dos soluciones: 1. \( w = \frac{-7 + 11}{6} = \frac{4}{6} = \frac{2}{3} \) 2. \( w = \frac{-7 - 11}{6} = \frac{-18}{6} = -3 \) Por lo tanto, las soluciones son: \[ w = \frac{2}{3}, -3 \]
