- 4 x^{3} = 36 x

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

Solution steps

- 4 x^{3} = 36 x

Move

36 x

to the left side

- 4 x^{3} - 36 x = 0

Factor

- 4 x^{3} - 36 x : - 4 x (x^{2} + 9)

- 4 x (x^{2} + 9) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x^{2} + 9 = 0

Solve

x^{2} + 9 = 0 : x = 3 i, x = - 3 i

The solutions are

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

z^{8} = 1

x^{3} - 8 x^{2} + 25 x - 26 = 0

x^{3} + 3 x - 5 = 0

15 x^{2} - 15 x^{4} = 0

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