Question about online summer camp 2021 Algebra blue group problem P6
Let a, b, c, d be the roots of x^4 − 5x^2 + 3x + 1. Evaluate
a^4 + b^4 + c^4 + d^4
I am having trouble doing this problem. While I could find a^2+b^2+c^2+d^2=19 using Vieta's formula, I am stuck and do not know how to get the answer the question is asking for. Can someone help?
