In an experiment, a scientist obtained the following data. 

  x  0  1        -1           
  y -5 -3 -15

Then by using "Newton's interpolating polynomial method", the scientist got the following polynomial : P2(x) = −5 + 2x − 4x(x−1)

Now, the scientist wants to do more experiment and got two more points (2, 39) and (−2,−9).

Therefore, the total data is the following.

x 0 1 -1 2 -2
y -5 -3 -15 39 -9

Again by apply Newton's interpolating polynomial method, the scientist obtained the following polynomial

P5(x) = a + 2x + bx(x−1) + cx(x−1)(x+1) + 3x(x−1)(x+1)(x+d).

Then,

a=

b=

c=

d=
