We want to find the zeros of this polynomial: p(x) = 2x^3 – x^2 - 8x + 4
Plot all the zeros (z-intercepts) of the polynomial in the interactive graph.

Step-by-step explanation:

The point is that any graphing calculator will work. We use Desmos on

The graph below is your complete answer.

You can actually find the zeros by factoring

p(x) = x^2(2x - 1) - 4(2x - 1)

p(x) = (2x - 1) (x^2 - 4)

p(x) = (2x - 1) (x - 2)(x + 2)

I have to hurry. If this is not enough, let me know.

the answer to this question is in the pic

you probably already have the answer but anyways it's b. 15.0
