Simplifying (-3)2 + (-2)2
This expression involves squaring negative numbers and then adding the results. Let's break it down step by step:
Understanding the Concept:
- Squaring a number means multiplying the number by itself. For example, 3 squared (3²) is 3 * 3 = 9.
- Negative numbers squared are always positive. This is because a negative number times a negative number equals a positive number. For example, (-2)² is (-2) * (-2) = 4.
Solving the Expression:
- Square (-3): (-3)² = (-3) * (-3) = 9
- Square (-2): (-2)² = (-2) * (-2) = 4
- Add the results: 9 + 4 = 13
Therefore, (-3)² + (-2)² is equal to 13.
