Answer: See explanation
Step-by-step explanation:
1. (x + 6)(x - 4)
x (x - 4) + 6 (x - 4)
x² - 4x + 6x - 24
x² + 2x - 24
2. (2x + 5)(x - 3)
2x (x - 3) + 5 (x - 3)
2x² - 6x + 5x - 15
2x² - x - 15
3. (3x + 2)(2x + 5)
3x (2x + 5) + 2 (2x + 5)
6x² + 15x + 4x + 10
6x² + 19x + 10
4. (2x - 1)(x - 5)
2x (x - 5) + -1 (x - 5)
2x² - 10x + -x + 5
2x² - 10x - x + 5
2x² - 11x + 5
