Question 27962
{{{ ( 5sqrt(2) + 3 )*( sqrt(2) - 2sqrt(3) ) }}}


ok, multiply out the brackets, as normal:
{{{ 5sqrt(2)*sqrt(2) + 3*sqrt(2) + 5sqrt(2)*(-2sqrt(3)) + 3*(-2sqrt(3)) }}}
{{{ 5sqrt(2*2) + 3sqrt(2) - 10sqrt(2*6) - 6sqrt(3) }}}
{{{ 5sqrt(4) + 3sqrt(2) - 10sqrt(12) - 6sqrt(3) }}}
{{{ 5*2 + 3sqrt(2) - 10sqrt(4*3) - 6sqrt(3) }}}
{{{ 10 + 3sqrt(2) - 10sqrt(4)*sqrt(3) - 6sqrt(3) }}}
{{{ 10 + 3sqrt(2) - 10*2*sqrt(3) - 6sqrt(3) }}}
{{{ 10 + 3sqrt(2) - 20sqrt(3) - 6sqrt(3) }}}
{{{ 10 + 3sqrt(2) - 26sqrt(3) }}}
