\n" );
document.write( "Let x represent the original number of students in group
\n" );
document.write( "    |Multiplying thru by x(x+2) so as all denominators = 1
\n" );
document.write( " 120(x+2) - 2x(x+2) = 120x
\n" );
document.write( " 120x + 240 - 2x^2 - 4x = 120x
\n" );
document.write( "    2x^2 + 4x - 240 = 0
\n" );
document.write( "     x^2 + 2x - 120 = 0    (Tossing out the negative solution for unit measure)
\n" );
document.write( "   (x +12)(x-10) = 0
\n" );
document.write( "           x = 10, the original number of students in group
\n" );
