Find the factored form of a polynomial function f whose roots are given. Then find values of the leading coefficient for which the coefficients of f in standard form are integers.Roots: 
, 
, 
, and 
A. f(x) = 60a(5x + 4)(3x + 2)(x + 2)2
a = k, for any integer k
B. f(x) = 60a(5x - 4)(3x - 2)(2x - 1)2
a = 60k, for any integer k
C. f(x) = 
(5x + 4)(3x + 2)(x + 2)2
a = 60k, for any integer k
D. f(x) = 
(5x - 4)(3x - 2)(2x - 1)2
a = 60k, for any integer k
Answer: D
