Dude am i doing your home work for you????WDH i’m bored. Here goes.1. b2. d3. d4. a (Have reservations about this question’s format) 5. b6. Either not correct or too complex for the scope of the remaining questions except you meant to write t^2 – sqrt (6)t – 9 = 0 in which case it is solved quadratically.7. b8. c9. d

Sqrt 2 Sqrt 3

Well, for the first one you get to FOIL!! And any day you get to FOIL is a good day!! (Remember that!) If you are not familiar with the FOIL technique, check out this video: http://www.youtube.com/watch?v=8h_lHZgVq_8After you do that on the first question, you end up with sqrt(2)*sqrt(2) + sqrt(3)*sqrt(3). Now, a square root is simply the opposite of a square…so if you are squaring a square root, you end up with the original number, right?This means that you have 2 + 3 = 5 for your first problem.For the rest of those problems, you need to look at the square root rules, http://www.mathwords.com/s/square_root_rules.htm.These rules allow you to break a square root down into the smallest numbers possible. Remember, a proper square root is an irrational number, which means that it can’t be broken down into any other combination of numbers.
