The expansion of (1 + x) ln (1 + x) into a power series of X Why is the answer x + ∑ (n from 2 to ∞) [(- 1) ^ (n) x ^ n / N (n-1)]. Why does n start with 2

The expansion of (1 + x) ln (1 + x) into a power series of X Why is the answer x + ∑ (n from 2 to ∞) [(- 1) ^ (n) x ^ n / N (n-1)]. Why does n start with 2

If I guess correctly, I should just expand ln (1 + x) into a power series of X, and then multiply by (1 + x) to get the answer
