You can put this solution on YOUR website!
straight away, you should have warning bells ringing, since \"+-6+%28x%2B5%29%5E2=120+\" can be altered to \"%28x%2B5%29%5E2=-20\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "From this point, we need to take square roots of both sides, to remove the squared term on the left. However, we then have \"sqrt%28-20%29\", which has no real solution. You then enter into Complex numbers and i am not sure you have done this topic.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Anyway, here goes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%2B5+=+sqrt%28-20%29\"
\n" ); document.write( "\"x%2B5+=+sqrt%28-1%2A4%2A5%29\"
\n" ); document.write( "\"x%2B5+=+sqrt%28-1%29sqrt%284%29sqrt%285%29\"
\n" ); document.write( "\"x%2B5+=+i%2Asqrt%284%29sqrt%285%29\"
\n" ); document.write( "\"x%2B5+=+i%2A2%2Asqrt%285%29\"
\n" ); document.write( "\"x%2B5+=+2sqrt%285%29i\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "--> \"x+=+2sqrt%285%29i+-+5\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "jon.
