Question

3)Dados D = (a + 3) e E = (2a² + 4x - 2), determine D . E. *
a) 4a³+ 4a²x + 6a²+ 12x – 6
b) 2a³+ 8a²x - 2a²+ 12x - 6
c) 5a³+ 4ax + 4a²+ 7x - 3
d) 2a³+ 4ax – 2a + 6a²+ 12x – 6​

Answer 1

Resposta:

D)

Explicação passo a passo:

3)Dados

D = (a + 3)

E = (2a² + 4x - 2), determine D . E.

= (a + 3).(2a² + 4x - 2)

= 2a^3 + 4ax - 2a + 6a^2 + 12x - 6

R.:

d) 2a³+ 4ax – 2a + 6a²+ 12x – 6​
