factor x^4-3x^3-4

factor

x^{4} - 3 x^{3} - 4

(x + 1) (x^{3} - 4 x^{2} + 4 x - 4)

Solution steps

x^{4} - 3 x^{3} - 4

Use the rational root theorem

= (x + 1) \frac{x ^{4} - 3 x ^{3} - 4}{x + 1}

\frac{x ^{4} - 3 x ^{3} - 4}{x + 1} = x^{3} - 4 x^{2} + 4 x - 4

= (x + 1) (x^{3} - 4 x^{2} + 4 x - 4)

(x + 1) (x - 3)^{2} > 0

(\frac{1}{5})^{27}

s^{2} + 6 s + 13 = 0

(- 4 x^{2})^{2}

\frac{10 !}{3 !}
