istim · Answer

I gues you know what to do with the denominator?

anonymous · Answer

yes im stuck at this part 

       2x - 1                       2x + 5 
-------------    -   -------------
(2x + 5)(2x - 5)         (2x - 1)(2x + 5)

What do i do after?

istim · Answer

What can you cross out now?

anonymous · Answer

well the 2x - 1 on the right side (denominator)

anonymous · Answer

i just dont get what to multiply the numerator with

istim · Answer

Well, the denominators are the same now.

istim · Answer

What does that mean you can do?

anonymous · Answer

can you like stop giving me hints. I am already stressed out and i know i did this before. Show me the steps after the part i gave and to the correct answer. Would appreciate it

So, what's your next step, with the knowledge that the denoms are the same.

razor99 · Answer

what kind of equation is that dada

istim · Answer

Ok. So what are you doing now.

anonymous · Answer

all im asking is that do you multiply the numerators by all the denominators 

eg. (2x - 1) (2x + 5)

razor99 · Answer

an algebra

anonymous · Answer

or just one denominator and yes razor this is algebra

anonymous · Answer

common denominator will be (2x+5)(2x-5)(2x-1)
(2x-1)^2-(2x+5)(2x-5)/ (2x+5)(2x-5)(2x-1)
4x^2-4x+1-4x^2+25/(2x+5)(2x-5)(2x-1)
26-4x/(2x+5)(2x-5)(2x-1)

istim · Answer

That person is right.

anonymous · Answer

the numerator should be -2(10x - 13)

anonymous · Answer

R u k with finding the common denominator?

anonymous · Answer

yeah i understand that part. Just not the part where you're multiplying
