(4)/(x^2-4)+(2x)/(x-2)+2/(x+2)=0
\n" ); document.write( "------------
\n" ); document.write( "Multiply thru by x^2-4 to get:
\n" ); document.write( "4 + 2x(x+2) + 2(x-2) = 0
\n" ); document.write( "---
\n" ); document.write( "4 + 2x^2+4x + 2x-4 = 0
\n" ); document.write( "2x^2 + 6x -2 = 0
\n" ); document.write( "-----
\n" ); document.write( "x^2 + 3x -1 = 0
\n" ); document.write( "---
\n" ); document.write( "x = [-3 +- sqrt(9 -4*-1)]/2
\n" ); document.write( "---
\n" ); document.write( "x = [-3 +- sqrt(13)]/2
