For a polynomial with real coefficients, use that roots come in complex conjugate pairs. Therefore, another root is 2-i (and we know for this example that the final root must be real). Write the factorised f...

Implement a fibonacci function which calculates the nth number of the fibonacci sequence.

def fib(n): if n <= 1: return n else: return(fib(n-1) + fib(n-2)) This is the code for a very basic version. This coud be used to explain how recursion works thanks to a relatively easy example.
