document.write( "The Diagonal of a rectangular room is 13ft long. one wall measures 7ft longer than the adjacent wall. 
\n" );
document.write( " 13^2 = x^2 + (x+7)^2
\n" );
document.write( " 169 = 2x^2 + 14x + 49
\n" );
document.write( "  2x^2 + 14x - 120 = 0
\n" );
document.write( "  x^2 + 7x - 60 = 0
\n" );
document.write( "factoring:
\n" );
document.write( " (x-5)(x+12) = 0
\n" );
document.write( "   x = 5  throwing out negative solution for unit measure
\n" );
document.write( " Dimensions of the room are 5ft by 12ft \n" );
