x^2(x^4+16)=8x^4
\n" ); document.write( "(x^2(x^4+16))/x^2=8x^4/x^2
\n" ); document.write( "x^4+16=8x^2
\n" ); document.write( "x^4-8x^2+16=0
\n" ); document.write( "((x^2-4)(x^2-4))=0
\n" ); document.write( "((x^2-4)(x^2-4))/(x^2-4)=0/(x^2-4)
\n" ); document.write( "x^2-4=0
\n" ); document.write( "x^2=4
