Answer:

x=196

Step-by-step explanation:

In order to solve this you just have to clear X fro the equation and solve:

[tex]2\sqrt{x} - 5=2\\ 2\sqrt{x}=2+5\\\sqrt{x}=7*2\\x=14^2\\x=196[/tex]Once you´ve calculated this you have the solution for the equation, that is x.

It is not an extraneous solution.

good job
