(x+16)^1/2=x-(x+17)^1/2

Given the equation

take the square of both sides then move the square root term to one side to get

Now take the square of both sides again to get

Use a calculator to find 4 solutions,

Plugging each of these back into the original equation, you would find that the first 3 solutions are extraneous, so the only solution is
