Subject: adding and multiplying radicals

	
Sons text is of no help and have found little on the internet.  She
wants them to factor to get their answer.  Example problems are listed
below.  Are there any rules to use as to when to place the number in
front of the square root sign?
no square root sign so will use sr to denote that
sr of 20 + sr of -20
