Answer:
f(x) = x³ - 5x² - 9x + 45
Step-by-step explanation:
Given x = a, x = b are the zeros of a polynomial, then
(x - a), (x - b) are the factors and f(x) is the product of the factors.
Here the zeros are x = - 3, x = 3 and x = 5, thus
(x + 3), (x - 3) and (x - 5) are the factors and
f(x) = (x + 3)(x - 3)(x - 5) ← expand the first pair of factors using FOIL
= (x² - 9)(x - 5) ← distribute
= x³ - 5x² - 9x + 45
U need to factor out the w's to make it easier to solve.

Answer:
5 years
Step-by-step explanation:
Interest earned ($) = Principal (amount $ invested) x Interest Rate (as a %) x Time (in years)
500 = 2500(.04)(t)
500 = 100t
t = 5 years
