|Issue 1495:||Missing parentheses in Limit Examples w/ brain malfunction on first prob (part 4)|

In addition to the brain malfunction on the first problem (:-), you're also missing some parentheses around the expression when you multiply by the "blah over blah" term, starting at about 6:05 and finishing at about 6:30. The original part of the expression needs to have enclosing parentheses due to the order of operations between addition and multiplication. Interesting example, BTW.

Actually, simply putting parens around the individual expressions would not work. For instance: lim (some expression) * (some expression) x->0 Is saying multiply the limit by this other term. The only appropriate way to do this would be to write a dividing line under the original expression and put a 1 in the denominator. Either way, I'm hoping the calculus students have seen someone multiply by a radical conjugate before and won't get confused.
