tolong bantu bsk di kumpul
Jawaban:
1. x² + 5x + 6 = 0
= (x + 3)(x + 2)
x = -2 dan -3
2. x² + 7x + 10 = 0
= (x + 5)(x + 2)
x = -5 dan -2
3. x² - 8x -20 = 0
= (x + 2)(x - 10)
x = -2 dan 10
4. x² - 5x - 6 = 0
= (x + 1)(x - 6)
x = -1 dan 6
5. x² + 10x - 24 = 0
= (x + 12)(x - 2)
x = -12 dan 2
6. x² + 14x - 32 = 0
= (x + 16)(x - 2)
x = -16 dan 2
7. x² - 7x +10 = 0
= (x - 2)(x - 5)
x = 2 dan 5
8. x² - 10x + 16 = 0
= (x - 2)(x - 8)
x = 2 dan 8
9. -15 - 2x + x²
= x² - 2x - 15 = (x - 5)(x + 3)
x = -3 dan 5
10. 9 - 6x + x² = 0
= x² - 6x + 9 = (x - 3)²
x = 3
