$c (x) = x^{4} - 5 x^{3} - 12 x^{2} - 22 x - 40$

Step 1

Set $x^{4} - 5 x^{3} - 12 x^{2} - 22 x - 40$ equal to $0$ .

$x^{4} - 5 x^{3} - 12 x^{2} - 22 x - 40 = 0$

Step 2

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

$x \approx - 1.79251847, 7.19872085$
