Question 85920
Question:


Simplify, (sq.rt.3 + 5)(sq.rt.3 -3) 


{{{ (sqrt(3) + 5 )( sqrt(3) - 3)}}}




Remove the parenthesis by multiplying each term.....




{{{ sqrt(3)* sqrt(3) - 3 * sqrt(3) + 5 * sqrt(3) - 5*3 }}}




==> {{{ 3 + 2* sqrt(2) - 15 }}}



==> {{{2 * sqrt(2) - 12 }}}...which is the simplified expression...



Hope you found the explanation useful.



Regards.
