Which of the following is the result of expanding the series12226x + 86x + 12

For this case we evaluate the series for each value of "n" from 0 to 3:

So:

We add similar terms and we have the result of expanding the series is:

Option C

Third option.

Step-by-step explanation:

Given  , We know that indicates that we need to start with and finish with ,

In order to expand the series, the procedure is the following:

This result matches with the third option.

$8

step-by-step explanation:

it is pretty much backwards.
