2 x^{3} - 18 x = 0

x = 0, x = - 3, x = 3

Solution steps

2 x^{3} - 18 x = 0

Factor

2 x^{3} - 18 x : 2 x (x + 3) (x - 3)

2 x (x + 3) (x - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 3 = 0 or x - 3 = 0

Solve

x + 3 = 0 : x = - 3

Solve

x - 3 = 0 : x = 3

The solutions are

x = 0, x = - 3, x = 3

z^{3} + 216 = 0

(3 x)^{3} (2 x)^{2} = 2300

y, y^{5} - 1 = x

x^{4} + 6 x^{2} - 3 = 0

- x^{3} + 5 x^{2} + 25 x - 125 = 0
