Find the Roots (Zeros) f(x)=x^4+x^3-6x^2-4x+5

$f (x) = x^{4} + x^{3} - 6 x^{2} - 4 x + 5$

Set $x^{4} + x^{3} - 6 x^{2} - 4 x + 5$ equal to $0$ .

$x^{4} + x^{3} - 6 x^{2} - 4 x + 5 = 0$

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

$x \approx - 2.4428629, - 1.39191323, 0.68355551, 2.15122063$
