The idea is to use the zero product property in reverse to go from the roots to the factorization. Then you expand out the polynomial using the distributive property.
x = 5 or x = 7 or x = -8
x-5 = 0 or x-7 = 0 or x+8 = 0
(x-5)(x-7)(x+8) = 0
(x-5)(x^2+x-56) = 0
x(x^2+x-56) - 5(x^2+x-56) = 0
x^3+x^2-56x -5x^2-5x+280 = 0
x^3-4x^2-61x+280 = 0
f(x) = x^3 - 4x^2 - 61x + 280
<h3>Answer: Choice D</h3>
Answer:
distance = 585600 m
Step-by-step explanation:
change 2 hours 20 minutes to seconds
2 hrs * 60 minutes/1hr * 60 sec/min = 7200 sec
20 minutes * 60 sec/min = 120 sec
2 hr 20 min = 7320 seconds
distance = rate * time
distance = 80 m/s * 7320 s = 585600 m
