Question

(x+4)²=25 mmmmkmkmkmkmkm

Answer 1

$\Large\mathsf\displaystyle{}\left(x + 4\right)^{2} = 25 \\\\ \Large\mathsf\displaystyle{}x + 4 = \pm \sqrt{25} \\\\ \Large\mathsf\displaystyle{}x + 4 = \pm5 \\\\ \Large\mathsf\displaystyle{}x + 4 = - 5 \\ \Large\mathsf\displaystyle{}x + 4 = 5 \\ \\ \Large\mathsf\displaystyle{}x = - 9 \\\Large\mathsf\displaystyle{}x = 1$

Solução:

$\Large\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ x_{1} = - 9 }}}\end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ x_{2} = 1 }}}\end{gathered} }$
