Question

Factoriza el siguiente polinomio:
P(x)=x^4 - x^3 - 7x^2 + x + 6
25 puntos porfiii es el ej 7

Answer 1

x^4-x^3-7 x^2+x+6 = 0

(x-3) (x-1) (x+1) (x+2) = 0

x-3 = 0 o x-1 = 0 o x+1 = 0 o x+2 = 0

x = 3 o x-1 = 0 o x+1 = 0 o x+2 = 0

x = 3 o x = 1 o x+1 = 0 o x+2 = 0

x = 3 o x = 1 o x = -1 o x+2 = 0

x = 3 o x = 1 o x = -1 o x = -2
