$g (x) = x^{4} + 5 x^{3} + 13 x^{2} + 19 x + 1$

Step 1

Set $x^{4} + 5 x^{3} + 13 x^{2} + 19 x + 1$ equal to $0$ .

$x^{4} + 5 x^{3} + 13 x^{2} + 19 x + 1 = 0$

Step 2

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

$x \approx - 2.73777163, - 0.05463121$
