8 = a^{3}

a = 2, a = - 1 + 3 i, a = - 1 - 3 i

Solution steps

8 = a^{3}

Switch sides

a^{3} = 8

For

x^{3} = f (a)

the solutions are

Simplify

a = 2, a = - 1 + 3 i, a = - 1 - 3 i

0 = 2 x^{3} + 8 x^{2} + 14 x + 24

- 2 x^{5} + 7 x^{2} - 3 = 0

5 = 2 x^{3} - 3.2

3 x^{4} + 15 x^{2} - 72 = 0

(x - 2) (x + 1) (2 x - 7) = 0
