u^{2} = - 5

u = 5 i, u = - 5 i

Solution steps

u^{2} = - 5

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

u = - 5, u = - - 5

- 5 = 5 i

- - 5 = - 5 i

u = 5 i, u = - 5 i

4 x^{2} - 4 x + 5

u^{2} = 20

- 0.5 x^{2} + 36 x - 522 = 0

2 x^{2} + 40 x = - 72

0 = - 810 a + a^{2} + 256064.9
