factor x^4+2x^3-2x-1

Solution

factor

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

Solution

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

Solution steps

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

Use the rational root theorem

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

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

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

Factor

x^{3} + 3 x^{2} + 3 x + 1 : (x + 1)^{3}

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