You can put this solution on YOUR website!
\"4-%281%2Fx%29+=+4x\" we have a fraction. Get rid of this by multiplying both sides, ie every term by x... this gives:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"4x+-+1+=+4x%5E2\". Collect all terms to one side, to give\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"4x%5E2+-+4x+%2B+1+=+0\". Now, hopefully factorise:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(2x-1)(2x-1) = 0\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so we have 2x-1 = 0
\n" ); document.write( "--> 2x = 1
\n" ); document.write( "--> x = 1/2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "jon.
