Find the Roots (Zeros) f(x)=-2x^3-2x^2+8x+3

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

Step 1

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

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

Step 2

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

$x \approx - 2.40423217, - 0.3547031, 1.75893528$
