sqrt{56} + sqrt{126} =
Break each sqrt separately.
sqrt{56} = sqrt{4} times sqrt{14}, where the square root of 4 is a perfect square.
sqrt{56} = 2(sqrt{14}).

=======================
sqrt{126} = sqrt{9} times sqrt{14}), where sqrt{9} is a perfect square.
sqrt{126} = 3(sqrt{14})
Now that we have the same radicand 14, we can add the radicals.
2(sqrt{14}) + 3(sqrt{14}) = 5(sqrt{14}) as the final answer.
============================================================
NOTE: We cannot break down sqrt{14} anymore because it is already in lowest terms.
