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

    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 \[\sqrt{6}\]

    \[3\sqrt{16*6}=3\sqrt{16}*\sqrt{6}\rightarrow 3*4\sqrt{6}\rightarrow 12\sqrt{6}\]
