0 = x^{3} - 9 x

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

Solution steps

0 = x^{3} - 9 x

Switch sides

x^{3} - 9 x = 0

Factor

x^{3} - 9 x : x (x + 3) (x - 3)

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

6 x^{3} - 31 x^{2} + 3 x + 10 = 0

y^{3} - 27 = 9 y^{2} - 27 y

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

x^{3} - 13 x - 12 = 0

x^{2} + x^{4} = 2
