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

x = - 1, x = 2

Solution steps

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

Switch sides

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

Factor

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

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 1 = 0 or x - 2 = 0

Solve

x + 1 = 0 : x = - 1

Solve

x - 2 = 0 : x = 2

The solutions are

x = - 1, x = 2

4 x^{4} - 33 x^{2} + 50 = 0

a^{4} - a^{2} = 2

2 x^{3} - 31 = 0

x^{4} - 5 x + 6 = 0

(2 x^{2} - 1)^{2} = 36
