You can put this solution on YOUR website!
6/x + 18/(x + 8) = 8
\n" );
document.write( "=> {6(x+8)+ 18x}/x(x+8) = 8
\n" );
document.write( "=> (24x+8)/(x^2+8x)=8
\n" );
document.write( "=> 24x+8 = 8x^2 + 64x
\n" );
document.write( "=> 8x^2 + 40x - 8 = 0
\n" );
document.write( "=> x^2 + 5x - 1 = 0
\n" );
document.write( "=> \n" );
