\[(8 +√11 )(8 –√11 ) \rightarrow 8*8-8\sqrt{11}+8\sqrt{11}-\sqrt{11}*\sqrt{11}\] which simplified you get \[64-11\] \[-\sqrt{11}*\sqrt{11}=-11\] the square root cancels out

oh i get that
anonymous
  • anonymous
yup just remember the FOIL concept and you will be good
anonymous
  • anonymous
okay i will so the answer then would be 64 +/11
anonymous
  • anonymous
No it would be 64 - 11

first thing you must look at is the square root. you can see that they aren't the same when adding radicals together they must have the same radical.

we can see the 1st one is \[2\sqrt{6}\] and the 2nd one is \[3\sqrt{96}\] you now have to find 2 multiples that would equal 96 so you can remain with a \[\sqrt{6}\]
anonymous
  • anonymous
\[3\sqrt{16*6}=3\sqrt{16}*\sqrt{6}\rightarrow 3*4\sqrt{6}\rightarrow 12\sqrt{6}\]
