Eliza solved a quadratic equation. Her work is shown below, with Step $2$ missing.
**What could Eliza have written as the result from Step $2$?**
$\begin{align}
\dfrac{1}{5}(x+3)^2-2&=18
\\\\
\dfrac{1}{5}(x+3)^2&=20&\text{Step }1
\\\\
&&\text{Step }2
\\\\
x+3&=\pm 10&\text{Step }3
\\\\
x=-13&\text{ or }x=7&\text{Step }4
\end{align}$
