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)

\frac{1}{3} + \frac{7}{9}

6 w^{2} - 4 u - 24 w + w u

(5 - i) (3 + 6 i)

\frac{9}{4} \div 3

2 (3 q) + q
