factor x^3+2x^2-19x-20

factor

x^{3} + 2 x^{2} - 19 x - 20

(x + 1) (x - 4) (x + 5)

Solution steps

x^{3} + 2 x^{2} - 19 x - 20

Use the rational root theorem

= (x + 1) \frac{x ^{3} + 2 x ^{2} - 19 x - 20}{x + 1}

\frac{x ^{3} + 2 x ^{2} - 19 x - 20}{x + 1} = x^{2} + x - 20

= (x + 1) (x^{2} + x - 20)

Factor

x^{2} + x - 20 : (x - 4) (x + 5)

= (x + 1) (x - 4) (x + 5)
