Kakak tolong dong ini cara penyelesaian nya bagaimana yah?
1. 6a+2c-7c+15
2. 3 pangkat 2+4p+2p+12
3. (4p+7q)(12p+8q)

Answer 1

1. 6a - 5c + 15
2. 3² = 9
9 + 4p + 2p + 12 = 21 + 6p
3. 48p² + 32pq + 84pq + 56q²
= 48p² + 116pq + 56q²

Answer 2

1. 6a+2c-7c+15= 6a-5c+15

2. 3 pangkat 2+4p+2p+12= 9+6p+12 =6p+21

3. (4p+7q)(12p+8q)= 48pkuadrat+32pq+84pq+56qkuadrat= 48p kuadrat+116pq+56q kuadrat
