x^{3} - 9 x^{2} + 23 x - 15

(x - 1) (x - 3) (x - 5)

Pasos de solución

x^{3} - 9 x^{2} + 23 x - 15

Utilizar el teorema de la raíz racional

= (x - 1) \frac{x ^{3} - 9 x ^{2} + 23 x - 15}{x - 1}

\frac{x ^{3} - 9 x ^{2} + 23 x - 15}{x - 1} = x^{2} - 8 x + 15

= (x - 1) (x^{2} - 8 x + 15)

Factorizar

x^{2} - 8 x + 15 : (x - 3) (x - 5)

= (x - 1) (x - 3) (x - 5)
