From another thread:

5/x+2 - 3(x+7)/x+2
i came up with 5/x+2 - 3x+21/x+2
is this answer correct?
FYI: It is best to post replies to questions within the original thread, so that the questions and answers are together and people know what it going on in the "conversation". Thank you.
What you have posted means the following:
. . . . .\(\displaystyle \L \frac{5}{x}\,+\,2\,- \,\frac{3(x\,+\,7)}{x}\,+ \,2\)
I will guess that you mean this:
. . . . .\(\displaystyle \L \frac{5}{x\,+\,2}\,-\,\frac{3(x\,+\,7)}{x\,+\,2}\)
If so, then it appears that you have expanded the one numerator correctly:
. . . . .\(\displaystyle \L \frac{5}{x\,+\,2}\,-\,\frac{3x\,+\,21}{x\,+\,2}\)
Now you need to combine the two fractions.
