Answer

$12n^2+13n-4$

Work Step by Step

RECALL: The distributive property states that for any real numbers a, b, and c: $a(b+c) = ab+ac \\a(b-c) = ab-ac$ Use the distributive property (which is shown above) to obtain: $=3n(4n-1) +4(4n-1) \\=3n(4n) +3n(-1)+4(4n) +4(-1) \\=12n^2-3n+16n-4$ Combine like terms to have: $=12n^2+13n-4$
