Identify the Zeros and Their Multiplicities P(x)=x^4-2x^3-240x-35

$P (x) = x^{4} - 2 x^{3} - 240 x - 35$

Step 1

Set $x^{4} - 2 x^{3} - 240 x - 35$ equal to $0$ .

$x^{4} - 2 x^{3} - 240 x - 35 = 0$

Step 2

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

$x \approx - 0.14580561, 7$
