factor x^3-6x^2-19x+84

factor

x^{3} - 6 x^{2} - 19 x + 84

(x - 3) (x + 4) (x - 7)

Solution steps

x^{3} - 6 x^{2} - 19 x + 84

Use the rational root theorem

= (x - 3) \frac{x ^{3} - 6 x ^{2} - 19 x + 84}{x - 3}

\frac{x ^{3} - 6 x ^{2} - 19 x + 84}{x - 3} = x^{2} - 3 x - 28

= (x - 3) (x^{2} - 3 x - 28)

Factor

x^{2} - 3 x - 28 : (x + 4) (x - 7)

= (x - 3) (x + 4) (x - 7)

f [(\frac{- 2}{5})^{- 2}]^{3}

(\frac{a + 1}{a})^{2}

(\frac{2 y - 1}{( 2 y )})^{2}

(7 - 4 y)^{3}

128 x^{3} + 18 y^{3}
