\"3%2Fx%2B2+%2B+7%2Fx-2+=+3\" Make the denominator common\r
\n" ); document.write( "\n" ); document.write( "\"3%28x-2%29%2F%28x%2B2%29+%2B7%28x%2B2%29%2F%28x-2%29+=+3+\" Get rid of the denominator\r
\n" ); document.write( "\n" ); document.write( "\"3%28x-2%29%2B7%28x%2B2%29=3%28x%2B2%29%28x-2%29\" Multiply out brackets\r
\n" ); document.write( "\n" ); document.write( "\"3x+-+6+%2B+7x+%2B+14+=+3+%28x%5E2+-+4%29+\"\r
\n" ); document.write( "\n" ); document.write( "\"+10x+%2B+8+=+3x%5E2+-+12\" Form a quadratic equation and make it look neat.\r
\n" ); document.write( "\n" ); document.write( "\"+0+=+3x%5E2+-+10x+-+20+\"\r
\n" ); document.write( "\n" ); document.write( "\"3x%5E2+-+10x+-+20+=+0\" Use the formula on it.\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\" \r
\n" ); document.write( "\n" ); document.write( "\"x+=+%2810+%2B-+sqrt%28100+-+4+%2A+3+%2A+-20%29%29%2F%282%2A3%29\"\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%2810+%2B-+sqrt%28+340+%29%29%2F%286%29+\" \r
\n" ); document.write( "\n" ); document.write( "I'm sure you can solve the formula from there.
