Answer 2

Answer:

You don’t specify what this equals to, so I will assume 0, as is standard practice. So, we start with sqrt(a+b) - sqrt(a-b) = 0.

Add sqrt(a-b) to both sides, to get sqrt(a+b) = sqrt(a-b).

Because both sides are sqrts, to remove that element, square both sides. This will get you a + b = a - b.

Get all the terms on one side and combine; subtract a from both sides and add b to both sides. This will lead to 2b = 0.

Divide both sides by 2, to isolate b (2b/2 = b).

b = 0.

Substitute b into both equations; you now have sqrt(a+0) - sqrt(a-0). This simplifies to sqrt(a) - sqrt(a). As you can tell, the answer is 0.
