$f (a) = \frac{2 x^{4} - 9 x^{2} - x + 2}{x^{2} - 2 x - 1}$

Step 1

Set $\frac{2 x^{4} - 9 x^{2} - x + 2}{x^{2} - 2 x - 1}$ equal to $0$ .

$\frac{2 x^{4} - 9 x^{2} - x + 2}{x^{2} - 2 x - 1} = 0$

Step 2

Graph each side of the equation. The solution is the x-value of the point of intersection.

$x \approx - 2, - 0.55138752, 0.42681725, 2.12457026$
