Jawablah pertanyaan diatas ​

Penjelasan dengan langkah-langkah:

1. 2(2a + 3) = 4a + 6

2. -a(a + b) = -a^2 – ab

3. (a + 4)(a + 3) = a^2 + 4a + 3a + 12 = a^2 + 7a + 12

4. (a – 6)(a – 5) = a^2 – 6a – 5a + 30 = a^2 – 11a + 30

5. (p + 1)(p + q – 1) = p^2 + pq – p + p + q – 1 = p^2 + pq + q – 1

Semoga membantu....
