anonymous · Answer

simplify it??

maddy1251 · Answer

@ceceburns2010 as a single logarithm.. Sorry! :(

anonymous · Answer

Np....are there options? or just a response?

anonymous · Answer

sorry its log((x−2)^2)

maddy1251 · Answer

Its just a response. I just don't know how to do it. How did you get that answer? @ceceburns2010

anonymous · Answer

Well it's just like expanding, although you aren't factoring, you need to find and combine like terms.  Also, simply -4, getting -2 and keeping the exponent of 2....make sense or not really??

anonymous · Answer

You keep X all together and keeping it as just X and not X^3

@ceceburns2010 Yeah! It makes sense. My pre-calc teacher is terrible at teaching. She doesn't explain these kind of problems so that leaves me drawing blanks.
