x^{3} + 216 = 0

x = - 6, x = 3 - 33 i, x = 3 + 33 i

Solution steps

x^{3} + 216 = 0

Move

216

to the right side

x^{3} = - 216

For

x^{3} = f (a)

the solutions are

Simplify

x = - 6, x = 3 - 33 i, x = 3 + 33 i

x^{3} - 3 x^{2} - 6 x + 8 = 0

x^{4} - 8 x + 16 = 0

2 y^{4} - 8 y^{2} + 6 = 0

x^{4} + 4 = 5 x^{2}

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