These two problems are part of a month long assignment that my teacher gave. We have never done anything similar to them in class, and I am at a loss of how to solve them. Help with either or both of them would be much appriecated (please explain your work)!
1. If the absolute value of x-3 is equal to k and k is greater than or equal to zero, which of the following is true?
a. x=k-3
b. x=k+3
c. x= k + and - 3
d. x= 3 + and - k
e. x= -3 + and - k
2.
24-6x
----------
x^2-5x+4
divided by
12x^2-3
------------
2x^2-x-1
I hope that last problem makes sense. :)

Thanks for everyone who participated in my last question,,
as you can see, I had another confused state about integrating, and these are the following.
NOte: all problems were started of an integral sign
1. (x+1)dx/x^2
I find that general power rule does not apply, does it?
or perhaps there are other ways..
then the following,, includes upper and lower limits,,
I know the steps how to solve but Im question wheter it will be udu or du/u
1. upper limits= 1
lower limits= 0
(1/(x+1)) - 1/(x-2))dx
my answer is ln|1+1|-ln|0+2|
or simply ln2-ln2
is this correct? if not! pls show me the correct way..
2.
upper limits= e
lower limits= 1
lnxdx/x
my answer in this one is ln | lne - ln1 |
is this correct? if not! pls show me the correct way..
Im only a beginner when solving this kind of problem,, pls dont mad at me,, hope you guys can help me out in this one..
