Jabarkan kemudian sederhanakanlah A(2a+3)(3a²–6a+9) B.(5p–4q)(25p²+20pq+16q²)

A)
2a.3a² + 2a.(-6a) + 2a.9 + 3.3a² + 3.(-6a) + 3.9
= 6a^3-12a²+18a+9a²-18a+27
= 6a^3 – 3a² + 27

A) (2a+3)(3a²-6a+9)
= 6a³ – 12a² + 18a + 9a² – 18a + 27
= 6a³ – 3a² + 27

b) (5p – 4q)(25p² + 20pq + 16q²)
= 125p³ + 100p²q + 80pq² – 100p²q – 80pq² – 64q³
= 125p³ – 64q³
