106. Worker efficiency. 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
b) Use the factored version of the formula to find N(3).
