Answer 1

Answer:

Here we are going to see the formula for the binomial expansion formula for 1 plus x whole power n.

(1 + x)n

(1 - x)n

(1 + x)-n

(1 - x)-n

Note :

When we have negative signs for either power or in the middle, we have negative signs for alternative terms.

If we have negative for power, then the formula will change from (n - 1) to (n + 1) and (n - 2) to (n + 2).

If we have negative signs for both middle term and power, we will have a positive sign for every term.
