8 x^{3} + 64 x^{2} + 120 x = 0

x = 0, x = - 3, x = - 5

Solution steps

8 x^{3} + 64 x^{2} + 120 x = 0

Factor

8 x^{3} + 64 x^{2} + 120 x : 8 x (x + 3) (x + 5)

8 x (x + 3) (x + 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 3 = 0 or x + 5 = 0

Solve

x + 3 = 0 : x = - 3

Solve

x + 5 = 0 : x = - 5

The solutions are

x = 0, x = - 3, x = - 5

c^{3} - 8 = 0

x^{3} - x^{2} - 4 x + 8 = 0

v^{4} - 0.8949 v^{2} + 0.028367 = 0

x, x^{3} + 5 y = 25

4 x^{3} + 12 a x^{2} - 16 a^{2} x = 0
