Question

- Seja P(x) = 2a² + b e Q(x) = a³ + 3ab + 4b². Calcule P(x). Q(x).

Answer 1

Resposta:

2a⁵ + 4b³ + 7a³b + 8a²b² + 3ab²

Explicação passo a passo:

P(x) = 2a² + b

Q(x) = a³ + 3ab + 4b²

P(x) . Q(x)

(2a² + b) . (a³ + 3ab + 4b²)

2a².a³ + 2a².3ab + 2a².4b² + b.a³ + b.3ab + b.4b²

2a⁵ + 6a³b + 8a²b² + a³b + 3ab² + 4b³

2a⁵ + 7a³b + 8a²b² + 3ab² + 4b³

2a⁵ + 4b³ + 7a³b + 8a²b² + 3ab²
