roots

x^{3} + 4 x

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

Solution steps

x^{3} + 4 x

The roots are the intercepts with the x-axis

(y = 0)

x^{3} + 4 x = 0

Factor

x^{3} + 4 x : x (x^{2} + 4)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

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

Solve

x^{2} + 4 = 0 : x = 2 i, x = - 2 i

The solutions are

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

x^{3} - 23 x^{2} + 22 x = 0

9 x^{8} - 72 x^{7} = 0

x^{3} - 2 x^{2} - 19 x + 20 = 0

x^{3} - 64

x^{5} + x^{3} + 8 x^{2} + 8 = 0
