See the entire solution process below:

First, we write this expression as:

#(a^3 - 4a^2)/((a - 4))#

Next, factor the numerator as:

#(a^2(a - 4))/((a - 4))#

Now, cancel the common term in the numerator and denominator:

#(a^2color(red)(cancel(color(black)((a - 4)))))/(color(red)(cancel(color(black)((a - 4))))) ->#

#a^2#: Where #a - 4 != # or #a != 4#
