Question 713229
multiply
(square root of 11 minus 3)(square root of 11 minus 3)
I FOIL and get square root of 11 times square root of 11 minus 3 square root of 11 minus 3 square root of 11 plus 9.
then i simplify and get 11 minus 6 square root of 11 plus 9
Write it: {{{11 -6sqrt(11) + 9}}}
now just add 9 and 11 and you have
{{{20-6sqrt(11)}}}
