factor 2x^4+x^3-19x^2-9x+9

factor

2 x^{4} + x^{3} - 19 x^{2} - 9 x + 9

(x + 1) (2 x - 1) (x + 3) (x - 3)

Solution steps

2 x^{4} + x^{3} - 19 x^{2} - 9 x + 9

Use the rational root theorem

= (x + 1) \frac{2 x ^{4} + x ^{3} - 19 x ^{2} - 9 x + 9}{x + 1}

\frac{2 x ^{4} + x ^{3} - 19 x ^{2} - 9 x + 9}{x + 1} = 2 x^{3} - x^{2} - 18 x + 9

= (x + 1) (2 x^{3} - x^{2} - 18 x + 9)

Factor

2 x^{3} - x^{2} - 18 x + 9 : (2 x - 1) (x + 3) (x - 3)

= (x + 1) (2 x - 1) (x + 3) (x - 3)

2 (x - 6)

(x + \frac{1}{2}) (x - \frac{1}{2})

(x + i y)^{2}

(1 + i)^{5}

(e^{t} - e^{- t})^{2}
