Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Consecutive Even Integers
Consecutive even integers are pairs of even numbers that follow one another in the number line, differing by 2. For example, if x is an even integer, the next consecutive even integer can be expressed as x + 2. Understanding this concept is crucial for solving problems involving even integers, as it allows for the formulation of equations based on their properties.

Difference of Squares
The difference of squares is a mathematical identity that states a² - b² = (a - b)(a + b). This concept is particularly useful when dealing with problems involving the squares of numbers, as it simplifies the process of finding the difference between them. In the context of the question, it helps to express the relationship between the squares of two consecutive even integers.

Setting Up Equations
Setting up equations is a fundamental skill in algebra that involves translating a word problem or mathematical statement into a mathematical expression or equation. In this case, recognizing the relationship between the two consecutive even integers and their squares allows for the creation of an equation that can be solved to find the integers. This process is essential for effectively tackling algebraic problems.
