{1, x, x(x-1), x(x-1)(x-2)} you want to find the linear combinations that will give you 1, x, x^2, x^3(adsbygoogle = window.adsbygoogle || []).push({});

a + a(x) + a(x(x-1)) + a(x(x-1)(x-2)) = 1

a + a(x) + a(x(x-1)) + a(x(x-1)(x-2)) = x

a + a(x) + a(x(x-1)) + a(x(x-1)(x-2)) = x^2

a + a(x) + a(x(x-1)) + a(x(x-1)(x-2)) = x^3

I don't know what to do from there
