$f (x) = x^{5} - 8 x^{4} + x^{3} - 9 x^{2} - 8 x + 3$

Step 1

Set $x^{5} - 8 x^{4} + x^{3} - 9 x^{2} - 8 x + 3$ equal to $0$ .

$x^{5} - 8 x^{4} + x^{3} - 9 x^{2} - 8 x + 3 = 0$

Step 2

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

$x \approx - 0.78159869, 0.28214052, 8.02977768$
