Answer:
1. (2x² - 1/400y²)² - (2x² + 1/400y²)²
Solve - (a - b)² = (a)² - 2ab + (b)²
(a + b)² = (a)² + 2ab + (b)²
= (2x²)² - 2 × 2x² × 1/400y² + (1/400y²)² - (2x²)² + 2 × 2x² × 1/400y² + (1/400y²)²
= 4x⁴ - x²/100y² + 1/160000y⁴ - (4x⁴ + x²/100y² +
1/160000y⁴)
= 4x⁴ - x²/100y² + 1/160000y² - 4x⁴ - x²/100y² -
1/160000y⁴
= 4x⁴ - 4x⁴ - x²/100y² - x²/100y² + 1/160000y⁴ -
1/160000y⁴
= - 2x²/100y²
