You can put this solution on YOUR website!
lowest common denominator is $\"x%5E2\"$ , so best suggestion is multiply the left and right members by $\"x%5E2\"$ . You will then solve a quadratic equation. Do the first two steps, simplify, and you should understand a fairly predictable solution path. The only reason you might not know how to start is forgotten what negative exponent means.\r

\n" ); document.write( "Multiply left and right by $\"x%5E2\"$ .........
\n" ); document.write( "......in fact when you do this you should find that the quadratic is factorable. \n" ); document.write( "
