Answer:
1. (y + 3)(y + 6)
y × (y + 6) + 3(y + 6)
y² + 6y + 3y + 18
= y² + 9y + 18
2. (2x - 5)(4x + 3)
2x × (4x + 3) - 5(4x + 3)
8x² + 6x - 20x - 15
= 8x² - 14x - 15
3. (2m + 8)(3m + 6)
2m × (3m + 6) + 8(3m + 6)
6m² + 12m + 24m + 36
= 6m² + 36m + 36
4. (d + 3)(d² - 3d + 16)
d × (d² - 3d + 16) + 3(d² - 3d + 16)
d³ - 3d² + 16d + 3d² - 9d + 48
= d³ + 7d + 48
5. (k - 4)(3k² + 5k + 7)
k × (3k² + 5k + 7) - 4(3k² + 5k + 7)
3k³ + 5k² + 7k - 12k² - 20k - 28
= 3k³ - 7k² - 13k - 28
Answer:
1. y² + 9y+ 18
2.8ײ - 14x - 15
3.6m² + 36m + 48
4. -d² + 13d + 48
5.11k² - 37k - 28
