factor 2x^3+11x^2-20x+7

factor

2 x^{3} + 11 x^{2} - 20 x + 7

(x - 1) (2 x - 1) (x + 7)

Solution steps

2 x^{3} + 11 x^{2} - 20 x + 7

Use the rational root theorem

= (x - 1) \frac{2 x ^{3} + 11 x ^{2} - 20 x + 7}{x - 1}

\frac{2 x ^{3} + 11 x ^{2} - 20 x + 7}{x - 1} = 2 x^{2} + 13 x - 7

= (x - 1) (2 x^{2} + 13 x - 7)

Factor

2 x^{2} + 13 x - 7 : (2 x - 1) (x + 7)

= (x - 1) (2 x - 1) (x + 7)

- 4 \leq 4 x + 4 \leq 8

7 (5) - 4 (1) = - 5

6 y^{2} - 13 y + 2

4 x^{2} - 9 y^{6}

\frac{5}{18} - \frac{1}{4} + \frac{7}{12}
