To solve the equation √2x - √50 = 0, we need to isolate the variable x.

First, let's simplify the equation by simplifying the square roots:

√2x - √50 = 0

√2x = √50

Now, square both sides of the equation to eliminate the square root:

(√2x)^2 = (√50)^2

2x = 50

Divide both sides of the equation by 2 to solve for x:

2x/2 = 50/2

x = 25

Therefore, the solution to the equation √2x - √50 = 0 is x = 25.
