(x + 2)(x + 5)= x² + 5x + 2x + 10
= x² + 7x + 10
(4x + 1)(3x - 2)
= 12x² - 8x + 3x - 2
= 12x² - 5x - 2
(- 3x - 5)(x - 6)
= - 3x² + 18x - 5x + 30
= - 3x² + 13x + 30

1) (x + 2)(x + 5)
(x² + 5x + 2x + 10)
x² + 7x + 10
2) (4x + 1)(3x - 2)
12x² - 8x + 3x - 2
12x² - 5x - 2
3) (- 3x - 5)(x - 6)
- 3x² + 18x - 5x + 30
- 3x² + 13x + 30
