Question 11203
Remove the parentheses using the distributive property:

2b(3+c)-b(2-c)
6b +2bc-2b + bc


Combine like terms:

4b + 3bc


Be VERY careful!  It's easy to make a mistake here, and there is really no way to check this except to work it again.  I missed this one myself and had to correct my error.  Let me know if you see any more!  EVERYBODY makes mistakes.
