A fourth degree polynomial equation is shown below.
1 answer:
<span>
4x^2-8x-12 =
(x -3) * (x +1)
4x^2-24x+32
</span><span>(x -4) * (x -2)
</span>Factored Form
(x -3) * (x +1) * <span>(x -4) * (x -2) = 0
x = 3
x = -1
x = 4
x = 2
All four roots are real numbers and so the graph crosses the x-axis four times. The graph of the equation would resemble a "W".
