You can put this solution on YOUR website!
assuming that z=x-(8/2x). If this is z=(x-8)/2x see below
\n" ); document.write( "2xz=2x^2-8 multiplying through by 2x
\n" ); document.write( "2x^2-2xz-8=0
\n" ); document.write( "x^2-zx-4=0
\n" ); document.write( "x=(z+/- sqrt(z^2+16))/2
\n" ); document.write( "----
\n" ); document.write( "if the other
\n" ); document.write( "2xz=x-8
\n" ); document.write( "2xz-x=-8
\n" ); document.write( "x(2z-1)=-8
\n" ); document.write( "x=(-8/(2z-1))
\n" ); document.write( "The parentheses matter.
