Kerjakan dengan cara yg lengkap
1. x² + 6x + 8 = (x + 2) (x + 4)
= x² + 2x + 4x + 8
= x² + 6x + 8
2. p² + 8p + 12 = (p + 2) (p + 6)
= p² + 6p + 2p + 12
= p² + 8p + 12
3. x² + 12x – 45 = (x – 3) (x + 15)
= x² + 15x – 3x – 45
= x² + 12x – 45
4. n² + 15n – 34 = (n – 2) (n + 17)
= n² + 17n – 2n – 34
= n² + 15n – 34
5. b² – 10b + 24 = (b – 4) (b – 6)
= b² – 6b – 4b + 24
= b² – 10b + 24
6. d² – 13d + 40 = (d – 5) (d – 8)
= d² – 8d – 5d + 40
= d² – 13d + 40
7. y² – 4y – 45 = (y + 5) (y – 9)
= y² -9y + 5y – 45
= y² – 4y – 45
8. z² – 7z – 30 = (z + 3) (z – 10)
= z² -10z + 3z – 30
= z² – 7z – 30
