8 x^{5} - 72 x = 0

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

Solution steps

8 x^{5} - 72 x = 0

Factor

8 x^{5} - 72 x : 8 x (x^{2} + 3) (x + 3) (x - 3)

8 x (x^{2} + 3) (x + 3) (x - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x^{2} + 3 = 0 or x + 3 = 0 or x - 3 = 0

Solve

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

Solve

x + 3 = 0 : x = - 3

Solve

x - 3 = 0 : x = 3

The solutions are

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

x^{5} - x^{3} - 2 x + 1 = 0

2 x^{4} + 7 x^{2} + 6 = 0

x^{3} - 8 x^{2} - 64 x = - 512

4 x^{3} - 6 x^{2} + 4 x - 1 = 0

x^{4} - x^{2} - 20 = 0
