Use FOIL. This stands for First, Outer, Inner, Last.
First: %28highlight%282n%29-3%29%28highlight%28n%29%2B4%29+=+2n%5E2
Outer: %28highlight%282n%29-3%29%28n%2Bhighlight%284%29%29+=+8n
Inner: %282n-highlight%283%29%29%28highlight%28n%29%2B4%29+=+-3n
Last: %282n-highlight%283%29%29%28n%2Bhighlight%284%29%29+=+-12
=======================
2n%5E2+%2B8n+-+3n+-12+=+highlight%282n%5E2+%2B5n+-12%29
