x^{3} + 3.2 x^{2} + 4.81 x = 0

x = 0, x = - \frac{8}{5} + i \frac{3}{2}, x = - \frac{8}{5} - i \frac{3}{2}

Solution steps

x^{3} + 3.2 x^{2} + 4.81 x = 0

Factor

x^{3} + 3.2 x^{2} + 4.81 x : x (x^{2} + 3.2 x + 4.81)

x (x^{2} + 3.2 x + 4.81) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x^{2} + 3.2 x + 4.81 = 0

Solve

x^{2} + 3.2 x + 4.81 = 0 : x = - \frac{8}{5} + i \frac{3}{2}, x = - \frac{8}{5} - i \frac{3}{2}

The solutions are

x = 0, x = - \frac{8}{5} + i \frac{3}{2}, x = - \frac{8}{5} - i \frac{3}{2}

n^{3} = \frac{8}{64}

24 x^{3} - 24 x^{2} - 48 x = 0

x^{6} = 4

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

x^{3} - 12 x + 2 = 0
