This question comes from ch.7.3 titled :Adding and subtracting rational Expressions with the same denominator and least common denominator.
2/x + 2/3=1 first i have to get a common denominator,yes? which would be 3x...so its 6/3x+2x/3x=1now i am lost
rational expression , need to show the domain the excluded value,set , the factor and the real numbers

Hi, i have 2 application questions about rational inequalities that i hope you will help me solve and explain to me how are they solved: 1)When successful new software is first introduced,...
I've multiplied it out so that they both have a common denominator of (x+4)(x-2) and now I'm confused on what to do next.
I'be tried this problem several times and keep getting stuck. I don't think I'm starting it right.
Rationalize the denominator in the expression -√2d t = ---- ...

The problem is : (3x+3/x^2+2x+1)+(x-1/x^2-1) ^2=squared ive been on a lot of math help websites but I cant seem to figure out how to solve this
Simplify this rational expression x^2+3x-7 x^2+5x-9 x^2-6x+14 ----------- - ------------- + --------------- x^2-2x-8...
(FIRST PART ALREADY ANSWERED AND NEW PART ADDED) Why do you find the domain of both the numerator and denominator in a rational equation? When do you do it?
For example, if you had: x-3 ------ 5x+3 you'd only find the domain and use the denominator. Why wouldn't you also do the numerator? And...
