u^{2} + 9 = 0

u = 3 i, u = - 3 i

Solution steps

u^{2} + 9 = 0

Move

9

to the right side

u^{2} = - 9

For

x^{2} = f (a)

the solutions are

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

u = - 9, u = - - 9

- 9 = 3 i

- - 9 = - 3 i

u = 3 i, u = - 3 i

x^{2} = 1 6^{2} - (83)^{2}

(4 x - 3)^{2} = 0

30 x^{2} - 18 x = 0

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

(2 x - 1) (3 x + 2) = 0
