Question

Please Help! I'll give a medal! I know I already posted this question but I need someone to explain it to me better.
Subtract (x+2/2x)-(x/x+3) Discuss and identify any possible restrictions that exist with (or in) the resulting rational expression.

Answer 1

\[\frac{x+2}{2x}-\frac{x}{x+3}\] right?

Answer 2

yes

Answer 3

first off, all your denominator must be \(\neq 0\) , those are restriction, hence
\(x\neq 0\) and \(x+3\neq 0\) or \(x\neq -3\) ok?

Answer 4

I ate all s after denominator and restriction, hehehe... they should be denominators and restrictions.

Answer 5

Huh? I am confused

Answer 6

why? that's the rule for a fraction has some meaning.

Answer 7

All the threes and zeros and xs look like they are all combined so it is confusing to me. Can we just solve the thing first, then look at the restrictions?

Answer 8

nope, restriction first ALWAYS

Answer 9

You must have restrictions before solving, so that if your solutions "violate" the restrictions, you get rid them off.

Answer 10

okay can you explain the restrictions a little more and explain how your getting them in words, I understand things better that way

Answer 11

if you have a fraction and the variable on the denominator, then the denominator must be not 0 . That is the way you find out the restriction

Answer 12

okay

Answer 13

those are examples of restrictions, not your problem
