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

Solution

factor

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

Solution

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

Solution steps

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

Use the rational root theorem

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

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

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