factor x^3-19x-30

Solution

factor

x^{3} - 19 x - 30

Solution

(x + 2) (x + 3) (x - 5)

Solution steps

x^{3} - 19 x - 30

Use the rational root theorem

= (x + 2) \frac{x ^{3} - 19 x - 30}{x + 2}

\frac{x ^{3} - 19 x - 30}{x + 2} = x^{2} - 2 x - 15

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

Factor

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

= (x + 2) (x + 3) (x - 5)
