Rationalize the denominator assume all expressions under radicals represent positive numbers.
\n" ); document.write( "(2-√y)/(3+√y) please help, I have trouble with these
\n" ); document.write( "------------------
\n" ); document.write( "Always multiply by the conjugate of the DEN. In this case it's
\n" ); document.write( "\"3+-+sqrt%28y%29\"
\n" ); document.write( "-------------------
\n" ); document.write( "That gives you:
\n" ); document.write( "\"%282-sqrt%28y%29%29%2A%283+-+sqrt%28y%29%29%2F%289-y%29\"
\n" ); document.write( "Then multiply the NUM
\n" ); document.write( "= \"%286+%2B+y+-+5sqrt%28y%29%29%2F%289+-+y%29\"\r
\n" ); document.write( "\n" ); document.write( "
