Hi;

so far I got to the point                    .5           -.5     
                                             -4.5x     - 7.5x      - 5
                                            ----------------------------
                                                                2
                                                      (3x-5)

I can not read that.


In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Re: Derivative

Why are the exponents still in there after you put it in radicals?/

Re: Derivative

The exponents are powers of x.
