$f (x) = 10 x^{4} - 4 x^{3} - 8 x^{2} + 3 x - 6$

Step 1

Set $10 x^{4} - 4 x^{3} - 8 x^{2} + 3 x - 6$ equal to $0$ .

$10 x^{4} - 4 x^{3} - 8 x^{2} + 3 x - 6 = 0$

Step 2

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

$x \approx - 1.07835073, 1.20268067$
