$f (x) = 2 x^{6} - 10 x^{5} - 23 x^{4} + 80 x^{3} + 28 x^{2} - 20 x + 9$

Step 1

Set $2 x^{6} - 10 x^{5} - 23 x^{4} + 80 x^{3} + 28 x^{2} - 20 x + 9$ equal to $0$ .

$2 x^{6} - 10 x^{5} - 23 x^{4} + 80 x^{3} + 28 x^{2} - 20 x + 9 = 0$

Step 2

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

$x \approx - 2.91760713, - 0.76514407, 2.49543758, 5.72194861$
