Use the distributive property to find the product of ((n+4)(n+2)

Question

i guess I'm supposed to use the FOIL pattern but I still don't get it 

Answer 1

First, Outer, Inner, Last

 

(n + 4)(n + 2)

First: n(n), or n²

Outer: n(2), or 2n

Inner: 4(n), or 4n

Last: 4(2), or 8

 

n² + 2n + 4n + 8

n² + 6n + 8
