x/3=4/x+1\r
\n" ); document.write( "\n" ); document.write( "multiply this equation by x then we get:
\n" ); document.write( "\"x%5E2%2F3+=+4+%2B+x\"\r
\n" ); document.write( "\n" ); document.write( "multiply it again by 3 the we get:
\n" ); document.write( "\"x%5E2+=+12+%2B+3x\"
\n" ); document.write( "<=> \"x%5E2+-+3x+-+12+=+0\"
\n" ); document.write( "Use abc formula to get the answer:
\n" ); document.write( "\"x1+=+%28-b+%2B+sqrt%28b%5E2+-+4%2Aa%2Ac%29%29%2F%282%2Aa%29\"
\n" ); document.write( "\"x1+=+%28-%28-3%29+%2B+sqrt%28%28-3%29%5E2+-+4%2A1%2A%28-12%29%29%29%2F%282%2A1%29\"
\n" ); document.write( "\"x1+=+%283+%2B+sqrt%289+%2B+48%29%29%2F2\"
\n" ); document.write( "\"x1+=+%283+%2B+sqrt%2857%29%29%2F2\"\r
\n" ); document.write( "\n" ); document.write( "\"x2+=+%28-b+-+sqrt%28b%5E2+-+4%2Aa%2Ac%29%29%2F%282%2Aa%29\"
\n" ); document.write( "\"x2+=+%28-%28-3%29+-+sqrt%28%28-3%29%5E2+-+4%2A1%2A%28-12%29%29%29%2F%282%2A1%29\"
\n" ); document.write( "\"x2+=+%283+-+sqrt%289+%2B+48%29%29%2F2\"
\n" ); document.write( "\"x2+=+%283+-+sqrt%2857%29%29%2F2\"\r
\n" ); document.write( "\n" ); document.write( "so the answers are:
\n" ); document.write( "\"x1+=+%283+%2B+sqrt%2857%29%29%2F2\" and \"x2+=+%283+-+sqrt%2857%29%29%2F2\"\r
