Solve the quadratic for x, then take the inverse cosine. For the second, multiply both sides of the equation by (x + 1)(x - 2). -Dan
1) On the first, would you consider factoring or the quadratic formula if it said $\displaystyle 2x^{2} - x - 1 = 0$? 2) Say $\displaystyle x \neq -1$ and $\displaystyle x \neq -2$ and add the fractions and solve.
