0.2 x^{3} - 0.2 x^{2} - 1.2 x = 0

x = 0, x = 3, x = - 2

Solution steps

0.2 x^{3} - 0.2 x^{2} - 1.2 x = 0

Factor

0.2 x^{3} - 0.2 x^{2} - 1.2 x : x (0.2 x^{2} - 0.2 x - 1.2)

x (0.2 x^{2} - 0.2 x - 1.2) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or 0.2 x^{2} - 0.2 x - 1.2 = 0

Solve

0.2 x^{2} - 0.2 x - 1.2 = 0 : x = 3, x = - 2

The solutions are

x = 0, x = 3, x = - 2

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

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

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

56 x^{6} - 336 x^{5} = 0

5 x^{5} - 80 x = 0
