Step-by-step Solution

Para resolver la ecuación \( 4.2 x^{2} + 27 = 244 \), primero restamos 27 de ambos lados: \[ 4.2 x^{2} = 244 - 27 \] \[ 4.2 x^{2} = 217 \] Ahora, dividimos ambos lados entre 4.2: \[ x^{2} = \frac{217}{4.2} \] Calculamos \( \frac{217}{4.2} \): \[ x^{2} \approx 51.6667 \] Ahora, tomamos la raíz cuadrada de ambos lados para encontrar \( x \): \[ x \approx \pm \sqrt{51.6667} \] Calculando la raíz cuadrada: \[ x \approx \pm 7.194 \] Por lo tanto, las soluciones son: \[ x \approx 7.194 \quad \text{y} \quad x \approx -7.194 \]

Quick Answer

Las soluciones son \( x \approx 7.194 \) y \( x \approx -7.194 \).
