- a^{3} + 3 a + 2 = 0

a = - 1, a = 2

Solution steps

- a^{3} + 3 a + 2 = 0

Factor

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

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

a + 1 = 0 or a - 2 = 0

Solve

a + 1 = 0 : a = - 1

Solve

a - 2 = 0 : a = 2

The solutions are

a = - 1, a = 2

2 x - x^{3} = 0

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

- 7 x^{3} - 6 x = 8

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

(r - 1) (r + 1)^{4} = 0
