1. x² + 5x + 6
2. x² - 19x - 4
3. 2x + 8
4. 6x² - 24x + 20
5. 6x³ - 46x² - 16x
Penjelasan dengan langkah-langkah:
1. (x + 2)(x + 3) = x² + 3x + 2x + 6
= x² + 5x + 6
2. (5x - 1)(x + 4) = 5x² + 20x - x - 4
= 5x² + 19x - 4
3. 2(x + 4) = 2x + 8
4. (3x - 5)(2x - 4) = 6x² - 12x - 10x + 20
= 6x² - 24x + 20
5. (6x² + 2x)(x - 8) = 6x³ - 48x² + 2x² - 16x
= 6x³ - 46x² - 16x
