Algebra 2 - Logirithims- What did I do wrong - Easy Best ANSWER?

How do you solve- what is the answer to:

log2(x) + log2(x + 2) = 3

I did this:

log2(x) + log2(x + 2) = 3
log2((x)(x+2)) = 3
log2(x^2 +2x) = 3
2^3 = x^2 +2x
8 = x^2 +2x
0 = x^2+2x - 8
o = (x+4)(x-2)
x = 4, -2

and I am wrong - please Help!!! Ist correct answer gets best answer

Medical School class?

My wife and I were watching a medical TV show, and while the Dr. was explaining what the procedure he was going to perform, he was scrubbing something MAD out of his hands!

So we were wondering, what week in medical school do you actually learn how to properly scrub your hands so intensilly like?!

We assume it's not the first week or two, because they are still worming out those that just won't cut it.
