\"2x%5E2+%2B+x+%2B6+=+0\" <===> \"x%5E2+%2B+x%2F2+%2B3+=+0\" \r
\n" ); document.write( "\n" ); document.write( "Hence \"alpha%2Bbeta+=+-1%2F2\" and \"alpha%2Abeta+=+3\"\r
\n" ); document.write( "\n" ); document.write( "For the new quadratic equation:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The coefficient of x = -(Sum of the roots)\r
\n" ); document.write( "\n" ); document.write( "= -\"%28alpha+%2B+1%2F%282%2Abeta%29+%2B+beta+%2B+1%2F%282%2Aalpha%29%29\".\r
\n" ); document.write( "\n" ); document.write( "=-\r
\n" ); document.write( "\n" ); document.write( "= -\"%28+-1%2F2+%2B%281%2F2%29%2A%28%28-1%2F2%29%2F3%29%29\" = 7/12\r
\n" ); document.write( "\n" ); document.write( "The constant in the quadratic equation = product of roots\r
\n" ); document.write( "\n" ); document.write( "= \"%28alpha+%2B+1%2F%282%2Abeta%29%29%28beta+%2B+1%2F%282%2Aalpha%29%29%29\".\r
