If anyone doesn't know how to do it, here's the extremely complex method of turning it into a second degree equasion.
(x+3)^2, is of course the same as:
(x+3)*(x+3)
take the first x, multiply it with the second x. Then multiply it with the second 3. Now take the first 3, multiply it with the second x, then multiply it with the second 3.
Add them together.
x^2 + 3x + 3x + 9.
Pat yourself on the back, you are now part of the elite.
Now teach this to a 12-year-old, because I'm sure that he or she will learn to mimic it within 15 minutes. Knowing how to do this doesn't really portray any sort of intelligence. Not knowing how to do this probably means that nobody's ever bothered to spend the 15 minutes needed to teach you this, or you've just forgotten, because it's a phenomenally useless piece of trivial information.
What WOULD show a level of intelligence, is if you've never heard of, or seen this method before, but you would manage to figure it out yourself.
