Tolong dong kak mau di kumpulin

Jawaban:

$a(3a + 8b) = (a times 3a) + (a times 8b) \ = {3a}^{2} + 8ab$

$- 5 {p}^{2} (6p - 3q) = ( - 5 {p}^{2} times 6p) + ( - 5 {p}^{2} times - 3q) \ = - {30p}^{3} + 15 {p}^{2} q \ = - 15 {p}^{2} (2 {p} + q)$

$3q(6 {p}^{2} +5pq - 4 {q}^{2} ) \ = (3q times {6p}^{2} ) + (3q times 5pq) + (3q times - 4 {q}^{2} ) \ = {18p}^{2} q + {15pq}^{2} - {12q}^{3} \ = 3q(2p - q)(3p + 4q)$

semoga membantu. (^_^)
