u^{3} - 64 = 0

u = 4, u = - 2 + 23 i, u = - 2 - 23 i

Solution steps

u^{3} - 64 = 0

Move

64

to the right side

u^{3} = 64

For

x^{3} = f (a)

the solutions are

Simplify

u = 4, u = - 2 + 23 i, u = - 2 - 23 i

r^{3} + r^{2} - 23 r - 35 = 0

12 x^{4} + 7 x^{3} + 49 x^{2} + 28 x + 4 = 0

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

x (x + 2) (x + 3) = - 1

3 x^{4} - 16 x^{3} + 24 x^{2} - 9 = 0
