3 x^{3} - 9 x^{2} - 54 x = 0

x = 0, x = - 3, x = 6

Solution steps

3 x^{3} - 9 x^{2} - 54 x = 0

Factor

3 x^{3} - 9 x^{2} - 54 x : 3 x (x + 3) (x - 6)

3 x (x + 3) (x - 6) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 3 = 0 or x - 6 = 0

Solve

x + 3 = 0 : x = - 3

Solve

x - 6 = 0 : x = 6

The solutions are

x = 0, x = - 3, x = 6

x^{3} = - 2 - 23 i

x^{3} + x^{2} = 16 x + 16

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

x^{3} + 12 x^{2} + 48 x + 64 = 0

y^{4} - 17 y^{2} = - 16
