Show that the Newton divided-difference polynomials 3 - 2(х + 1) +0(х + 1)х + (х + 1)x(х — 1) and -1+4(х+ 2) - 3(х + 2)(х + 1) + (x+2)(х+ 1)х keth interpolate the data (-2, –1), (–1,3), (0, 1), (1, –1), (2, 3). Why do the polynomials not violate the uniqueness property of interpolating polynomials?

Show that the Newton divided-difference polynomials
3 — 2(х + 1) +0(х + 1)х + (х + 1)x(х — 1) and
—1+ 4(х + 2) - 3(х + 2)(х + 1) + (х+ 2)(х + 1)x
both interpolate the data (-2, –1), (–1,3), (0,1), (1, –1), (2,3).
