x^{3} - 15 x = 0

x = 0, x = - 15, x = 15

Solution steps

x^{3} - 15 x = 0

Factor

x^{3} - 15 x : x (x + 15) (x - 15)

x (x + 15) (x - 15) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 15 = 0 or x - 15 = 0

Solve

x + 15 = 0 : x = - 15

Solve

x - 15 = 0 : x = 15

The solutions are

x = 0, x = - 15, x = 15

- 3 x^{2} x = - 7

x (1 - x)^{2} = \frac{1}{10}

t^{4} - 5 t^{3} + 5 t^{2} + 17 t - 42 = 0

3 x^{4} - 4 x^{3} - 12 x^{2} - 4 = 0

6 x^{3} + x^{2} - 24 x - 4 = 0
