Which of the following is a polynomial function in factored form with zeros at –2, 5, and 8?

a)f(x) = (x – 2)(x + 5)(x + 8)

b)f(x) = x3 – 11x2 + 14x + 80

c)f(x) = x3 + 11x2 + 14x – 80

d)f(x) = (x + 2)(x – 5)(x – 8)

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
