A polynomial p(x) = x^2 - 2x - 8 is plotted, and the curve cuts the x-axis at two points marked below. Using the graph and a check, identify the two zeroes.

Question

Accepted Answer

-2 and 4. x^2 - 2x - 8 = (x - 4)(x + 2), zeroes 4 and -2. These match the x-axis crossings.

A polynomial $p (x) = x^{2} - 2 x - 8$ is plotted, and the curve cuts the $x$ -axis at two points marked below.
