Answer

Explanation:

Step1: Define the formula

La fórmula para el eje de simetría de una ecuación cuadrática con raíces $x_1$ y $x_2$ es $x=\frac{x_1 + x_2}{2}$.

Step2: Sustituir valores

Dado que $x=-3$ y $x_1 = 4$, sustituimos en la fórmula: $-3=\frac{4 + x_2}{2}$.

Step3: Resolver para $x_2$

Multiplicamos ambos lados por 2: $-3\times2=4 + x_2$, es decir, $-6 = 4+x_2$. Luego restamos 4 de ambos lados: $x_2=-6 - 4=-10$.
