$\"+x%5E%282%2F3%29-2x%5E%281%2F3%29-8=0+\"$
\n" ); document.write( "Let $\"1%2F3+=+z\"$
\n" ); document.write( " $\"+x%5E%282z%29-2x%5Ez-8=0+\"$
\n" ); document.write( " $\"x%5E%282z%29+-+2x%5Ez+%2B+1+=+8+%2B+1\"$
\n" ); document.write( " $\"%28x%5Ez+-+1%29%5E2+=+9\"$
\n" ); document.write( " $\"x%5Ez+-+1+=+3\"$
\n" ); document.write( " $\"x%5Ez+=+4\"$
\n" ); document.write( "Take the zth root of both sides
\n" ); document.write( " $\"x+=+4%5E%281%2Fz%29\"$
\n" ); document.write( "Since $\"z+=+1%2F3\"$ ,
