If you wanna keep from factoring it yourself (which is a pain in the butt), you can FOIL each of those answers until you find one that matches the expression in the question. You're familiar with FOILing right?
No im not familiar with foiling
Oh okay FOIL is an acronym for First, Outside, Inside and Last. That's the order of what you multiply things by so, you multiply the first two numbers, the two outside numbers, the two inside numbers, then the last two numbers. I'll draw it so you can see what I mean. FOILing is a lifesaver and you'll need it for a lot of things
