You can put this solution on YOUR website! i still have problems with this...
6b-3/b+4
---
Assuming there are no parentheses you get:
6b - (3/b) +4
----
lcd = b
----
Rewrite each term with the lcd as its denominator:
(6b^2)/lcd - (3/lcd) + (4b/lcd)
-----
Combine the numerators over the lcd:
-----
(6b^2-3+4b)/b
======================
Note: If there are parentheses you should post them.
