X^{2} + 9 = 0

X = 3 i, X = - 3 i

Solution steps

X^{2} + 9 = 0

Move

9

to the right side

X^{2} = - 9

For

x^{2} = f (a)

the solutions are

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

X = - 9, X = - - 9

- 9 = 3 i

- - 9 = - 3 i

X = 3 i, X = - 3 i

x^{2} - \frac{4}{3} x + \frac{4}{9} = 0

4 x^{2} = - 2

x (x + 3) - 40 = 0

7 x^{2} + 2 = 8 x

x, 9 x^{2} + 12 x y + 4 y^{2} - 22 x - 84 y + 129 = 0
