Why can't The answer be p<=3 OR p<= -3 ? How does it become -3<= p <= 3 ? Thank you!
Think of the number 0 for example. This is $\displaystyle \displaystyle \begin{align*} \leq 3 \end{align*}$, but it's not $\displaystyle \displaystyle \begin{align*} \leq -3 \end{align*}$. How are you supposed to know which is correct?
