simplify complex fraction with 3 fractions top and bottom

[one23itsjustme]

I'm glad you start out the video by mentioning that there are 2 different ways to solve the problem...because I saw an earlier video, and I thought WHOA! What is going on here....I would have done it a different way...however, it would be even better to see both ways, so that we could compare methods? just a thought, it would also help me to decide which method I like better. (again, just thoughts because I notice I work out some problems different than the teacher too).

why didn't you factor the trinomial above the x^2 and x^3 instead you go directly in cross multiplying. or is it just not factorable?

you really helped mam!!!

thank yu!!! :)

i hope my algebra prof. does the same as you do ^^

She is so awesome!!

Question how do i solve a problem with if the denominator is 1 over 4 minus 3 over "X" squared? Pls reply

@CrimsonGuard1992 Sorry but I only answer followup questions to the problem done in the video.

[Eloheim1977]

where is the 13 and 14 being factored at??

[lightsabre5511]

in the second example did u factor by completing the square?

[robichaudd]

No, I factored by unfoiling (or, trial and error). To see videos on that go to my channel and search on "factor trinomial".

[myanime09]

um,..I would just like to know why you did not multiply the bottom w/ the LCD and so as the top in the first step that you showed...

[robichaudd]

That would be a different method than I used in this video. Here I turned the top into a single fraction (with its own LCD), turned the bottom into a single fraction (with its own LCD), then multiplied the top fraction by the reciprocal of the bottom fraction.

The other method you refer to works too - you could multiply top and bottom by LCD of all fractions and go from there.

your doing the problem, but not explaining why the LCD on top is X3 and the proper steps in solving it.
