start by canceling the 2's, then ...
can you finish?
multiply the single terms by the (-1)'s ...
Ok let's see if I can type this out correctly.
#1)
So distribute the first expression through the parenthesis.
Multiply the last two expressions.
The denominator of expression two can be factored with some moving around.
Now multiply each expression by the conjugate of the denominator to get the radicals gone.
EDIT: I'll keep the post here just because it took me so long, but look above at skeeter's post for a much quicker, better simplification.
