factor x^3-39x-70

Solution

factor

x^{3} - 39 x - 70

Solution

(x + 2) (x + 5) (x - 7)

Solution steps

x^{3} - 39 x - 70

Use the rational root theorem

= (x + 2) \frac{x ^{3} - 39 x - 70}{x + 2}

\frac{x ^{3} - 39 x - 70}{x + 2} = x^{2} - 2 x - 35

= (x + 2) (x^{2} - 2 x - 35)

Factor

x^{2} - 2 x - 35 : (x + 5) (x - 7)

= (x + 2) (x + 5) (x - 7)

Popular Examples

∣ 10 - 10 x ∣ < - 2

2 x - 4 + 6 x < 10 x - 7

factor 2b^3-54 factor

2 b^{3} - 54

x/2+(4x-12)/5 = 7/10 x

\frac{x}{2} + \frac{4 x - 12}{5} = \frac{7}{10} x

simplify (1/x+1/y)/(1/(x^2)-1/(y^2))simplify

\frac{\frac{1}{x} + \frac{1}{y}}{\frac{1}{x ^{2}} - \frac{1}{y ^{2}}}
