- 4 x^{3} + 16 x = 0

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

Solution steps

- 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

x^{4} - 5 x^{2} - 36

x^{3} - 81 = 0

x (x - 1) (x + 2) - 2 = 0

x^{3} - 31 x - 30 = 0

12000 x^{3} - 85800 x^{2} - 300000
