1. 16x² - 49
2. 25x² - 40x + 16
3. 27y³ + 64
5. -20z² + 13z - 2
= (4x)² - 7²
= 16x² - 49
= (5x)² - 2 × 5x × 4 + 4²
= 25x² - 40x + 16
= (3y)³ + 4³
= 27y³ + 64
= -4z × 5z - 4z × (-2) + 5z - 2
= -20z² + 8z + 5z - 2
= -20z + 13z - 2

= 16x² - 49
= (5x)² - 2 × 5x × 4 + 4²
= 25x² - 40x + 16
= (3y)³ + 4³
= 27y³ + 64
= -4z × 5z - 4z × (-2) + 5z - 2
= -20z² + 8z + 5z - 2
