So the solutions for $ x $ are $ x = 0, 2, 3 $. Since $ x = \sqrt{u} $, we square each solution to find the corresponding $ u $-values:

["How to Solve for $ x $ and Find Corresponding $ u $-Values: $ x = 0, 2, 3 $", "Understanding how to solve equations involving square roots is essential in algebra and many real-world applications, from physics to finance. If you’ve encountered the solution $ x = 0, 2, 3 $, you may be wondering how these values connect to a variable like $ u $, especially when $ x $ is expressed as $ x = \sqrt{u} $.
