Solve x^4+x^3-4x^2+x+1=0 | Microsoft Math Solver By Factor theorem, x-k is a factor of the polynomial for each root k Divide x^ {4}+x^ {3}-4x^ {2}+x+1 by x-1 to get x^ {3}+2x^ {2}-2x-1 Solve the equation where the result equals to 0
$x^4+x^3+x^2+x+1$ irreducible over $\\mathbb F_7$ The answer claims that x4 +x3 +x2 + x + 1 x 4 + x 3 + x 2 + x + 1 is irreducible over F7 F 7 I can check that it has no roots in the field, but why can't it be written as a product of two quadratics? I tried the method of undetermined coefficients:
