Let \"3x%5E2+-+20x+%2B3p+%2B+4++=+0\".\r
\n" ); document.write( "\n" ); document.write( "==> \"x%5E2+-+%2820%2F3%29x+%2B+%283p+%2B+4%29%2F3++=+0\".\r
\n" ); document.write( "\n" ); document.write( "Now if one root is a, then by hypothesis, the other root is 4a.\r
\n" ); document.write( "\n" ); document.write( "==> \"-%28a%2B4a%29+=+-20%2F3\", and \"a%284a%29+=+4a%5E2+=+%283p+%2B+4%29%2F3\".\r
\n" ); document.write( "\n" ); document.write( "==> \"a+=+4%2F3\", and \"4%2816%2F9%29+=+%283p+%2B+4%29%2F3\".\r
\n" ); document.write( "\n" ); document.write( "==> \"64%2F9+=+%283p+%2B+4%29%2F3\". ==> \"p+=+52%2F9\"
