x^{3} - x^{2} - 20 x = 0

x = 0, x = - 4, x = 5

Solution steps

x^{3} - x^{2} - 20 x = 0

Factor

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

x (x + 4) (x - 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 4 = 0 or x - 5 = 0

Solve

x + 4 = 0 : x = - 4

Solve

x - 5 = 0 : x = 5

The solutions are

x = 0, x = - 4, x = 5

x^{6} + 117 x^{3} - 1000 = 0

(2 x - 1)^{3} = 27

0 = 2 x^{3} - x^{2} - 3 x

3 (x^{2} - 14) (x^{2} + 36) = 0

n^{3} = 10
