What are the x-intercepts of the function f (x) = - 2x2 - 3x + 20?

(-4, 0) and

and (4, 0)

(-5, 0) and (2, 0)

(-2, 0) and (5, 0)

If you would like to find the x-intercepts of the function f (x) = - 2 * x^2 - 3 * x + 20, you can calculate this using the following steps:

f (x) = - 2 * x^2 - 3 * x + 20

f (x) = - (2x - 5) * (x + 4)

1. x = - 4

2. x = 5/2

(x, y) = (-4, 0)

The correct result would be (-4, 0).
