Question

We want to find the zeros of this polynomial:

p(2) = (2x - 1)(x+3)(x + 1)(x - 2)
Plot all the zeros (x-intercepts) of the polynomial in the interactive graph.

Answer 1

How do you find the zeros of a polynomial graphically?

Explanation:

If we graph this polynomial as y = p(x), then you can see that these are the values of x where y = 0. In other words, they are the x-intercepts of the graph. The zeros of a polynomial can be found by finding where the graph of the polynomial crosses or touches the x-axis.
