You can put this solution on YOUR website!
solve: (3/n)-(7/sqrt(n))-6 =0
\n" ); document.write( "Multiply through by \"n\" to get: \r
\n" ); document.write( "\n" ); document.write( "3-7sqrt(n)=6n
\n" ); document.write( "Then -7sqrt(n)=6n-3
\n" ); document.write( "Square both sides to get:\r
\n" ); document.write( "\n" ); document.write( "49n=36n^2-36n+9
\n" ); document.write( "36n^2-85n+9=0
\n" ); document.write( "(4n-9)(9n-1)=0
\n" ); document.write( "n=9/4 or n=1/9
\n" ); document.write( "Checking you will find that n=9/4 is extraneous.
\n" ); document.write( "Hope this helps.
