u^{2} = - 16

u = 4 i, u = - 4 i

Solution steps

u^{2} = - 16

For

x^{2} = f (a)

the solutions are

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

u = - 16, u = - - 16

- 16 = 4 i

- - 16 = - 4 i

u = 4 i, u = - 4 i

3 x^{2} + 5 x - 322 = 0

(7 x + 6)^{2} = 16

(- 0.2) x^{2} + 80 x - 3.95 = 0

2 x^{2} - 27 x + 36 = 0

(x - 4) (x - 6) = 0
