Explanation
The sum of two odd integers (e.g., 3 + 5) is always an even number (e.g., 8). That’s because odd + odd = even .

Explanation
Step 1: Understand the problem The problem asks for the product of √-2 × √-2. Step 2: Calculate the product √-2 × √-2 = (√-1 × √2) × (√-1 × √2) = (√-1)² × (√2)² = i² × 2 = -1 × 2 = -2

Explanation
Disjoint sets have no elements in common. Therefore, their intersection is the null set (∅) .

Explanation
First polynomial: 8x² + 10x - 25 Second polynomial: 5x² - 9x - 10 (8x² + 10x - 25) - (5x² - 9x - 10) = 8x² + 10x - 25 - 5x² + 9x + 10 = 3x² + 19x - 15
