Question 331468: In a study of worker efficiency at Wong
Laboratories it was found that the number of components
assembled per hour by the average worker t hours after
starting work could be modeled by the formula
N(t)=-3t^3+23t^2+8t
a) Rewrite the formula by factoring the right-hand side
completely.
b) Use the factored version of the formula to find N(3).

N(t)=-3t^3+23t^2+8t
N(t)=-t(3t^2-23t-8)
N(t)=-t((3t^2-24t+t-8))
N(t)=-t(3t(t-8)+1(t-8))
N(t)=-t(3t+1)(t-8)
..
N(3)=-3(9+1)(3-8)
N(3)=150
