factor 2x^3+x^2-23x+20

factor

2 x^{3} + x^{2} - 23 x + 20

(x - 1) (2 x - 5) (x + 4)

Solution steps

2 x^{3} + x^{2} - 23 x + 20

Use the rational root theorem

= (x - 1) \frac{2 x ^{3} + x ^{2} - 23 x + 20}{x - 1}

\frac{2 x ^{3} + x ^{2} - 23 x + 20}{x - 1} = 2 x^{2} + 3 x - 20

= (x - 1) (2 x^{2} + 3 x - 20)

Factor

2 x^{2} + 3 x - 20 : (2 x - 5) (x + 4)

= (x - 1) (2 x - 5) (x + 4)

34 - 9

\frac{2}{4} + \frac{3}{10}

6 x^{2} + 17 x - 3

\frac{30}{54}

9 x + 2 + (3 x - 7) - 8 x
