WOW DUDE! I forgot about this test everyday thing and REALLY was not ready for that. I did pretty good on the first test most likely because I reallyyyyy learned that after I failed that test in the beginning of the year. So I always knew Logs pretty good:
If you have Log(5)25=2 you switch everything around to make sense. The base (5) goes first.
The answer should be: 5^2=25
If a log has no base the base is understood to be 10. If there is an e in the log then it is a natural log.
Something that I'm not too fresh with is completing the square. I do not know how but I just forgot how to do it for the test this week.

Alrighty well i think i can help with this.
ReplyDeleteokay so first you would move your constant term to the right side of the equal sign. Next, divide your linear term by 2 and then square it. Then, take the answer you get after dividing the linear term by 2 and add it to both sides of the equation. Next. you would factor the perfect square trinomial. Lastly, take the square root of each side and solve.
Remember you answer will have a positive and negative number. Also, always write your answer in point form!!!!
