Finding the n-order derivative dny / DX ^ n of function y = ln (x ^ 2 + 3x + 2)

Finding the n-order derivative dny / DX ^ n of function y = ln (x ^ 2 + 3x + 2)

y=ln(x^2+3x+2)
y'=(2x+3)/(x^2+3x+2)=1/(x+1)+1/(x+2)
So the n-order derivative of Y is (- 1) ^ (n-1) * (n-1)! / (x + 1) ^ n + (- 1) ^ (n-1) * (n-1)! / (x + 2) ^ n
