Problem

Construct a $4$th degree polynomial $x^4+ax^3+bx^2+cx+d$ that meets as many of the following conditions as you can: the sum of the roots is $1$, the sum of the squares of the roots is $2$, the sum of the cubes of the roots is $3$, and the sum of the $4$th powers of the roots is $4$.


Solution

$x^4-x^3-\tfrac{1}{2}x^2-\tfrac{1}{6}x+\tfrac{1}{24}$
