You can put this solution on YOUR website!
let the two numbers be x and y
\n" ); document.write( "given that x+y=6--------->(1)
\n" ); document.write( " and x*y=7----------->(2)
\n" ); document.write( "from (2) x=7/y,putting this in equation (1)
\n" ); document.write( "we get
\n" ); document.write( "7/y+y=6
\n" ); document.write( "7+y^2/y =6
\n" ); document.write( "7+y^2=6y
\n" ); document.write( "Y^2-6y+7=0
\n" ); document.write( "solving this we get x=1.58 and -4.41
\n" ); document.write( "taking positive value
\n" ); document.write( "put the valuein (1)
\n" ); document.write( "we get x=4.42
\n" ); document.write( "checking 4.42+1.58=6
\n" ); document.write( "4.42*1.58=6.998=7
\n" ); document.write( "so thex=4.42 y=1.58
\n" ); document.write( " \n" ); document.write( "
\n" );
