i have an algebra trig. problem i can't figure out.

simplify:

(x^2 - 4)^1/2 (3) (2x+1)^2 (2) + (2x+1)^3 (1/2) (x^2 - 4)^-1/2 (2x)

the answer in the book says:
(2x+1)^2 (8x^2 + x - 24) OVER (x^2 - 4)^1/2


im so stuck. can someone help me get from the problem to the answer?

Rich people are already buying land on the moon ... but why??

the moon is there for everyone so should humans have a right to go and buy land on the moon?

it just annoys me that people think they can buy land on something that has been visited once and then do what they want with it.... i can imagine in the future seeing the moon been terraformed and its natural look been destroyed by humans... should the moon be left alone but be there for small teraformaing like building for space science and building for astronauts that visit the moon etc... should the moon become another Las Vegas style city

i would prefer the moon staying as it is but with humans visiting it in small times rather than building a huge city complexe on it for people to live on =[

so if you get what i mean lol probably not haha please answer

Do you believe aliens have abducted humans?
I don't believe that, let alone that aliens have even ever came to earth. What about you?

You can sign up - it's free. I prefer the card tests - I fail miserably at the remote viewing tests. :( I like it that the site keeps a record of your attempts. :)

Have you ever taken these tests? How'd you do? :)

(P.S. Please don't be snide if you don't believe in psychic phenomena. It's ok to be a skeptic, it's NOT ok to be rude. Thanks!)
