How do you find the product #4n(2n^3p^2-3np^2+5n)+4p(6n^2p-2np^2+3p)#?
Clear the parentheses by distributing the coefficients
There are no like terms, so this is as far as you can go.
You can factor by grouping, but if you do that, there was no point in distributing in the first place.
Maybe you consider this step as a simplification:
Factor out an additional
Factor out one more
Distributing these coefficients brings back the first answer, which was:
