Find the LCD of the rational expressions.

Find the LCD of the pair of rational expressions m − 18 m + 1 =====// , =======// 6m^4 9m Thanks for you help in advance. MY answer was wrong which was, 56m^4

So I have the problem u^2-2u/u^2-6u+9+4/4u-12. So I was figuring out the LCD and I came out with 4(u-3)^2 but the book says (u-3)^2. What happens to the 4. If you factor them out you ...show more

Find the least common denominator for the following trio of rational expressions. 6 ---------- p^2+13p+40 3 --------- p^2+6p-16 9 -------- p^2+3p-10 Really no idea ...show more

Will the denominator be a "least" common denominator, an LCD?

I know how to do rational expressions , but in order to do one where you have x + numerator/denominator then the divide symbol then another numerator/denominator, how would you solve what's on the left side. So x is a term by itself and it's not over...

Like I look everywhere on aim for expressions and they didn't have no good expressions that I can choose from. Im looking for Buddy Icons, Emoticons and Sounds. I couldn't find no good sounds to choose from. If anybody knows any good sites besides aim...

Hey guys. I have a project due in couple weeks. I'm almost done I just need one more question and I can not find it anywhere. The question is "Why must you restrict the domain when working with rational expressions or equations?" If you could...
