<reasoning>

Aplicar la raíz cuadrada a ambos lados

\[

$$\begin{aligned} (x - 7)^2 &= 25 \\ x - 7 &= \pm\sqrt{25} \\ x - 7 &= \pm 5 \end{aligned}$$

\]

Resolver para x

\[

$$\begin{aligned} x &= 7 \pm 5 \\ x_1 &= 7 + 5 = 12 \\ x_2 &= 7 - 5 = 2 \end{aligned}$$

\]

Identificar las opciones correctas

\[

$$\begin{aligned} x &= 12 \quad \text{(Opción D)} \\ x &= 2 \quad \text{(Opción F)} \end{aligned}$$

\]
