D^{2} + 9 = 0

D = 3 i, D = - 3 i

Solution steps

D^{2} + 9 = 0

Move

9

to the right side

D^{2} = - 9

For

x^{2} = f (a)

the solutions are

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

D = - 9, D = - - 9

- 9 = 3 i

- - 9 = - 3 i

D = 3 i, D = - 3 i

x^{2} - 32 = 4 x

x^{2} + 16 x + 0 = 0

x^{2} - 9 x + 14 = 0

x, 1200 = x^{2} + 4 x y

s^{2} + 4 s + 6
