Answer:

1. x² + 3x - 18

x(x - 3) + 6(x - 3)

(x-3)(x+6)

3. 18x² + 3x - 15

3(6x² + x - 5)

3(6x - 5)(x + 1)

2. 3x² - 9x - 12

3(x² - 3x - 4)

3(x + 1)(x - 4)

4. 5x² + 32x + 12

(5x² + 2x) + (30x + 12)

x(5x + 2) + 6(5x + 2)

(5x + 2)(x + 6)

5. 3x³ + 24

3(x³ + 8)

3(x + 2)(x² - 2x + 2²)

3(x + 2)(x² - 2x + 4)
