q^2-4/q^2-4+4=0
\n" ); document.write( "Just put q^2=x and rewrite the equation as
\n" ); document.write( "x-(4/x-4)+4=0
\n" ); document.write( "that is, x^2-20=0
\n" ); document.write( "=> x^2=20 and squaure root both sides yields
\n" ); document.write( "x= 20^0.5
\n" ); document.write( "and q=20^0.25 \n" ); document.write( "
