You can put this solution on YOUR website!
I think you mean critical point where $\"df%2Fdx=0\"$
\n" ); document.write( " $\"f=x%5E3-3x%5E2%2B2x%2B2\"$
\n" ); document.write( " $\"df%2Fdx=3x%5E2-6x%2B2=0\"$
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( " $\"x+=+%28-%28-6%29%2B-+sqrt%28+%28-6%29%5E2-4%2A3%2A2+%29%29%2F%282%2A3%29+\"$
\n" ); document.write( " $\"x+=+%286%2B-+sqrt%28+36-24+%29%29%2F%286%29+\"$
\n" ); document.write( " $\"x+=+%286%2B-+sqrt%28+12+%29%29%2F%286%29+\"$
\n" ); document.write( " $\"x+=+%286%2B-+2%2Asqrt%283%29%29%2F%286%29+\"$
\n" ); document.write( " $\"x+=+1%2B-+sqrt%283+%29%2F3+\"$ \n" ); document.write( "

\n" );
