Question 763293

{{{(sqrt(2) +1)(sqrt( 2) - 3)}}}

{{{(sqrt(2))^2-3sqrt(2) +sqrt( 2) - 3}}}

{{{2-2sqrt(2) - 3}}}

{{{-2sqrt(2) - 1}}}

{{{-2*1.41 - 1}}}

{{{-2.82 - 1}}}

{{{-3.82 }}}

or, simply like this:

{{{(sqrt(2) +1)(sqrt( 2) - 3)}}}

{{{(1.41 +1)(1.41 - 3)}}}

{{{(2.41)(-1.58)}}}

{{{-3.82}}}
