This solution is not efficient and may cause overflow due to factorial computation. A better solution is based on Legendre’s formula . nwu bursary application

Take out the constant 4 from the integral. We can factor the polynomial x^3-x^2-x+1 using the rational root theorem, which guarantees that for a polynomial of the form a_nx^n+a_{n-1}x^{n-1}+\\dots+a_0 there is a rational … nwu botanical garden
