Question 387744: Add. Simplify if possible
(3r)/(r^(2)-25) + (r)/(r-5)
for this I ended up with
r(r+8)/(r-5)(r+5)
is this right???

You can put this solution on YOUR website!
Add. Simplify if possible
3r%2F%28r%5E2-25%29+%2B+r%2F%28r-5%29
= (((3r/(r^2-25) + r(r+5)/(r^2-25)}}}
= %28r%5E2%2B8r%29%2F%28r%5E2-25%29
= r(r+8)/(r-5)(r+5) Same thing.
------------------
for this I ended up with
r(r+8)/(r-5)(r+5)
is this right???
