2. c) is a quadratic equation if you let \displaystyle \begin{align*} x = s^2 \end{align*}, giving \displaystyle \begin{align*} x^2 + 3x - 6 = 0 \end{align*}. Solve for \displaystyle \begin{align*} x \end{align*} using the Quadratic Formula, then use this to evaluate \displaystyle \begin{align*} s \end{align*}.
