Here's the step by step to solve that. But I'm not good in explaining this so I hope you'll understand it.

 6√8+2√50-2√32

Factor the Square Roots.

6
√8 = 6√4*2
2√50 = 2√25*2
2
√32 = 2√16*2

Next, 

6
√4*2 ( Square root of 4 is 2, times it to 6  (The whole number outside the square root ey), the answer will be) 12√2
2
√25*2 ( Square root of 25 is 5, times it to 2  (The whole number outside the square root ey), the answer will be) 10√2
2
√16*2 ( Square root of 16 is 4, times it to 2 (The whole number outside the square root ey), the answer will be) 8√2

Now, the equation is simplified.

12√2 + 10√2 - 8√2

The rule: PEMDAS//MDAS
Addition:
12
√2 + 10√2 = 22√2
Subration:
22
√2 - 8√2 = 14√2

The answer is 14
√2. :) You may ask a question on the part that you didn't that clearly understand.
