OpenStudy (sarahezzmck):

\[\frac{ x-5 }{x ^{2} -3x-10 } \times \frac{ x+2 }{ x ^{2}+-12 }\]

OpenStudy (sarahezzmck):

sorry, took me awhile.

OpenStudy (loser66):

1/ correct x^2 + - 12. I don't understand 2/ factor the first denominator what do you have?

OpenStudy (sarahezzmck):

i meant \[x ^{2}+x-12 \] for teh denominator

OpenStudy (sarahezzmck):

**the

OpenStudy (sarahezzmck):

-5 and 2 for the first denominator?

OpenStudy (loser66):

yup, and fact tor the second one

OpenStudy (loser66):

I mean factor denominator of the second term

OpenStudy (sarahezzmck):

thats what im having trouble with, I think its -4 and 3 since they mulitply to 12 but they add to 1 not x...

OpenStudy (sarahezzmck):

wait isn't x the same as 1?

OpenStudy (loser66):

nope, it simplest form for real roots. we cannot factor it . let it there if we cannot do anything on it. so, just cancel what we can factor. dat sit

OpenStudy (sarahezzmck):

so, the answer is just \[\frac{ 1 }{ (x+2) (x-5) }\]? I'm confused
