4 x^{3} = 16 x

x = 0, x = - 2, x = 2

Solution steps

4 x^{3} = 16 x

Move

16 x

to the left side

4 x^{3} - 16 x = 0

Factor

4 x^{3} - 16 x : 4 x (x + 2) (x - 2)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 2 = 0 or x - 2 = 0

Solve

x + 2 = 0 : x = - 2

Solve

x - 2 = 0 : x = 2

The solutions are

x = 0, x = - 2, x = 2

1 - 9 x - 6 x - x^{3} = 0

(x - 3) (x + 4) (x + 5) (x - 4) = 180

6 - 3 (x + 1) = - 4 x^{2} (1 - x)

3 x^{4} - 3 x^{3} - 1 x^{2} = 0

z \cdot z^{3} + 15 = 16.66
