factor x^3-31x+30

Solution

factor

x^{3} - 31 x + 30

Solution

(x - 1) (x - 5) (x + 6)

Solution steps

x^{3} - 31 x + 30

Use the rational root theorem

= (x - 1) \frac{x ^{3} - 31 x + 30}{x - 1}

\frac{x ^{3} - 31 x + 30}{x - 1} = x^{2} + x - 30

= (x - 1) (x^{2} + x - 30)

Factor

x^{2} + x - 30 : (x - 5) (x + 6)

= (x - 1) (x - 5) (x + 6)

Popular Examples

5 x^{2} = - 11 x + 7

factor 81x^2-100y^2 factor

81 x^{2} - 100 y^{2}

77 = 11 \cdot h

(x-1/2)(2x^2-2x-12)>= 0

(x - \frac{1}{2}) (2 x^{2} - 2 x - 12) \geq 0

simplify (-8n+4)/(11n(n+1))*(4n^2)/(-10n+5)simplify

\frac{- 8 n + 4}{11 n ( n + 1 )} \cdot \frac{4 n ^{2}}{- 10 n + 5}
