$f (x) = x^{8} + 10 x^{7} - 30 x^{6} - 50 x^{5} + 80 x^{4} + 50 x^{3} - 30 x^{2} - 10 x + 1$

Step 1

Set $x^{8} + 10 x^{7} - 30 x^{6} - 50 x^{5} + 80 x^{4} + 50 x^{3} - 30 x^{2} - 10 x + 1$ equal to $0$ .

$x^{8} + 10 x^{7} - 30 x^{6} - 50 x^{5} + 80 x^{4} + 50 x^{3} - 30 x^{2} - 10 x + 1 = 0$

Step 2

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

$x \approx - 1.69876603, - 0.71845247, - 0.3563688, 0.08267392, 0.58866258, 1.39188051, 2.80608177$
