4 x^{3} - 256 x = 0

x = 0, x = - 8, x = 8

Solution steps

4 x^{3} - 256 x = 0

Factor

4 x^{3} - 256 x : 4 x (x + 8) (x - 8)

4 x (x + 8) (x - 8) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 8 = 0 or x - 8 = 0

Solve

x + 8 = 0 : x = - 8

Solve

x - 8 = 0 : x = 8

The solutions are

x = 0, x = - 8, x = 8

x, x^{3} + y^{3} + z^{3} = 42

- 6 x^{4} + 38 x^{3} - 45 x^{2} + 26 x - 5

2 x^{3} - x^{2} = 1

2 x^{4} = - 64

x^{2} - x^{4} = \frac{1}{16}
