Question 190229
N(t)=3t^3 + 23^t2 - 8t.
N(t) = t(3t^2 + 23t - 8)
N(t) = t(3t^2 +24t-t-8)
N(t) = t(3t(t+8) - (t+8))
N(t) = t(t+8)(3t-1)
================================
 
a) Rewrite the formula by factoring the right-hand side
completely.

b) Use the factored version of the formula to find N(3).
N(3) = 3*11*8 = 264
