Identify the first step when solving for x in the following equation. \( \sqrt{4 x}=x-2 \) Divide by 4 on both sides. Square both sides. Subtract x from both sides. Add 2 to both sides.

The first step to solving \( \sqrt{4 x} = x - 2 \) is to square both sides. This eliminates the square root, giving you \( 4x = (x - 2)^2 \). Just remember, squaring both sides might introduce extraneous solutions, so you'll want to check your answers at the end! Once you have squared both sides, you can expand the right-hand side to get \( 4x = x^2 - 4x + 4 \). Then, tantalizingly combine like terms to form a quadratic equation, which is always a fun challenge! Keep those mathematical gears turning!
