Gaussian quadrature

[6] ['Brute force' calculation of Gaussian quadrature weights and nodes]
Let
w₁f(x₁) +w₂f (x₂)
(3)
be a quadrature formula to approximate the integral ₁ f(x).
Determine the weights {w₁, w2} and nodes {x₁, x2} such that (3) is exact
(no error) for f(x) = 1, x, x², and x³. Then show that the formula is not
exact for f(x) = x4 and conclude that the degree of exactness is N = 3.
