$\"x%5E2-4x%2B8=0\"$ x=__ Plus __ and minus__.
\n" ); document.write( " using the formula $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$ we get
\n" ); document.write( " $\"x+=+%28-%28-4%29+%2B-+sqrt%28%28-4%29%5E2-4%2A1%2A8%29%29%2F%282%2A1%29+\"$
\n" ); document.write( " $\"x+=+%284%2B-+sqrt%28-16%29%29%2F2\"$
\n" ); document.write( " (2+2i) OR ( 2-2i )
\n" ); document.write( " +(2+2i) OR - (2i-2)
