factor x^3-3x^2-9x+2

factor

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

(x + 2) (x^{2} - 5 x + 1)

Solution steps

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

Use the rational root theorem

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

\frac{x ^{3} - 3 x ^{2} - 9 x + 2}{x + 2} = x^{2} - 5 x + 1

= (x + 2) (x^{2} - 5 x + 1)

(4 x - 7) (x + 3)

\frac{3 x ^{3} - 6 x ^{2}}{x ^{2} + x - 6}

(x - 20) (x - 25) (x - 30)

\frac{( 5 + i ) ^{2} ( 3 - 2 ( 4 + i ) )}{( 1 + i ) ^{3}}

(\frac{3}{8} a + \frac{1}{6} b)^{4}
