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

x = 0, x = 1 + 2, x = 1 - 2

Solution steps

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

Factor

x^{3} - 2 x^{2} - x : x (x^{2} - 2 x - 1)

x (x^{2} - 2 x - 1) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x^{2} - 2 x - 1 = 0

Solve

x^{2} - 2 x - 1 = 0 : x = 1 + 2, x = 1 - 2

The solutions are

x = 0, x = 1 + 2, x = 1 - 2

x^{4} - 4 x^{2} + 5 = 0 - 1

(x^{3} - 2) = - 25

0 = x^{3} - 4 x^{2} - 25 x + 100

x^{3} + 2 x^{2} - 10 x = 0

r^{3} + 2 r^{2} + r = 0
