Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Square Root Property
The square root property states that if x^2 = k, then x = ±√k. This property is essential for solving quadratic equations, as it allows us to isolate the variable by taking the square root of both sides. It is particularly useful when the equation can be rearranged into the form of a perfect square.

Rearranging Equations
Rearranging equations involves manipulating the equation to isolate the variable of interest. In the context of the given problem, we first need to move all terms to one side to set the equation to zero, which is a common practice in solving equations. This step is crucial for applying the square root property effectively.
