X^5 - 3X^4 - 10X³ + 52X - 72X + 32 Divido entre (X - 1)
X^5 - 3X^4 - 10X³ + 52X - 72X + 32 = (X - 1)(X^4 - 2X³ - 12X² + 40X - 32)
Ahora a (X^4 - 2X³ - 12X² + 40X - 32) lo divido entre (X - 2)
(X^4 - 2X³ - 12X² + 40X - 32) = (X - 2)(X³ - 12X + 16)
Ahora a (X³ - 12X + 16) lo divido entre (X - 2)
(X³ - 12X + 16) = (X - 2)(X² + 2X - 8)
Ahora: (X² + 2X - 8) = (X - 2)(X + 4)
Finalmente agrupo
(X - 1)(X - 2)(X - 2)(X - 2)(X + 4)
(X - 2)³(X - 1)(X + 4)
X^5 - 3X^4 - 10X³ + 52X² - 72X + 32 = (X - 2)³(X - 1)(X + 4)
X + 4 = 0; X = - 4
Rta: X = - 4
