# Use binomial theorem to expand (x - 1)^{7}

Hint:

### The binomial expansion is , here n ≥ 0 . We are asked to use binomial theorem to expand (x - 1)7 .

## The correct answer is: (x + y)n

Step 1 of 2:

The given expression is (x - 1)^{7} , here x = x & y = -1 . The value of n=7, hence there are 7+1=8 terms in the expressions.

Step 2 of 2:

Substitute the values of (x - 1)^{7} in the binomial equation to get the expansion:

Thus, the expansion is:

For the expansion of an expression (x + y)n , we would have n+1 terms. This is something you need to keep in mind.
