  1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  2. Wait patiently for a helper to come along.
  3. Once someone helps you, say thank you and close the thread with:
    +close
    
  4. Feel free to nominate the person for helper of the week in #helper-nominations
  5. Do not ping the mods, unless someone is breaking the rules.
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

start by factoring everything

formal latch
#

let me show you my progress

#

This is one of the other 1000 failed attempts

devout plinth
#

your first step was right

#

on your second step, try to resolve everything in the bracket before multiplying

formal latch
#

but i don't see how

#

i don't have anything in common there

devout plinth
#

combine the three fractions being added/subtracted into a single one

formal latch
#

😭 what

#

i only see multiplying first fraction with x+5

#

the second with x-5

#

and then i can combine them

#

in a single one

#

actually no

#

if i knew the second step, i would've done it by now

devout plinth
#

$\frac{x+2}{x-5} - \frac{x-2}{x+5} - \frac{27-5x}{25-x^2}$

#

can you find the common denominator?

formal latch
#

x ?

devout plinth
#

no

formal latch
#

great

#

i'm actually really good at this

devout plinth
#

would it help if i

#

$\frac{x+2}{x-5} - \frac{x-2}{x+5} - \frac{27-5x}{-(x-5)(x+5)}$

#

so now i have to multiply first fraction with x+5
the second with x-5 and then i can combine them, because i still don't have an actual common denominator

#

i'm getting confused

devout plinth
formal latch
#

i nailed it, finally

#

let me see where i can get

#

finally

#

the answer is 9

#

i got tricked by the minus you gave as common factor [-(x-5)(x+5)], i didn't see it in the beginning

#

thank you very much
