Show the steps please.
a)
Find common denominator, multiply both sides by denominator. Solve basic equation for x. The answer is 1/2 if you need a reference.
b)
Add 5 to both sides, square both sides, add 4 to both sides, take square root.
2. c) is a quadratic equation if you let $\displaystyle \displaystyle \begin{align*} x = s^2 \end{align*}$, giving $\displaystyle \displaystyle \begin{align*} x^2 + 3x - 6 = 0 \end{align*}$. Solve for $\displaystyle \displaystyle \begin{align*} x \end{align*}$ using the Quadratic Formula, then use this to evaluate $\displaystyle \displaystyle \begin{align*} s \end{align*}$.
