Respuesta de la multiplicación (-3a(n+4)b(n+1))(-4a(n+2)b(n+3))

Answer 1

[ -3a(n+4)b(n+1) ] × [ -4a(n+2)b(n+3) ]

= [ (-3an-12a)(bn+b) ] × [ (-4an-8a)(bn+3b) ]

= ( -3abn²-3abn-12abn-12ab ) × ( -4abn²-12abn-8abn-24ab )

= ( -3abn²-15abn-12ab ) × ( -4abn²-20abn-24ab )

= 12a²b²n⁴ + 60a²b²n³ + 72a²b²n² + 60a²b²n³ + 300a²b²n² + 360a²b²n + 48a²b²n² + 240a²b²n + 288a²b²

= 12a²b²n⁴ + 120a²b²n³ + 420a²b²n² + 600a²b²n + 288a²b²
