Find all values of x which satisfy the equation.

1. If x(x-3) = 0 then
a. x= 0 only
b. x= 3 only
c. x=0 or x=-3
d. x=0 or x=3

2. If If x(x - 1) = 2, then
A. x = 1 or x = 2
B. x =-1 or x = -2

I've just started college, and I haven't yet decided what I want to major in. I'm currently regidtered as a Chem major, but I haven't even really decided what I want to do yet. I want to pursue a career in dentistry, and was given the option of some type of biological science (biology) or chemistry. I'm also very interested in the current research on stem cells, and such. I really want to get into the major healthcare problems of today that haven't really been perfected, such as helping people with lost limbs, dental fractures, etc. So basically I would like to know that if I do change my major to those fields, what occupations can they lead me to, what companies, and is there even a job market for them???

I got a test question like that and they give me 4 different pair of equations.. I know that if a pair of equations have the same slope those two equations would be parallel. but I would have to find the slope of all 8 equations.. Any one knows a faster way?

(a) x -2y=3 and x -2y=7
(b) x+y=1 and x+y= -2
(c) x+y=1 and z+y= -2
(d) x+y=3 and x-y=5
(e) x-y=7 and x-y=14

I don't need the answer, I need to know HOW to solve it.. THANKS A LOT!!!!!!!!!

change in entropy =change in enthalpy / temperature
From this formula ,entropy change seems to be inversely propostional related with temperature,wheras it is found that on increasing temperature,entropy of system increases.
Kindly explain the contradiction.Thanks
