sqrt (2x+5)=5-sqrt (x+2)\r
\n" ); document.write( "\n" ); document.write( "square both sides
\n" ); document.write( "2x +5 = 25 -10 sqrt (x+2) +x +2
\n" ); document.write( "collect terms\r
\n" ); document.write( "\n" ); document.write( "x+10 sqrt (x+2)=22
\n" ); document.write( "10 sqrt (x+2)=22-x
\n" ); document.write( "square both sides\r
\n" ); document.write( "\n" ); document.write( "100 (x+2)=484 -44x +x^2
\n" ); document.write( "100x +200=484-44x + x^2
\n" ); document.write( "x^2-144x+284=0\r
