z^{2} + 9 = 0

z = 3 i, z = - 3 i

Solution steps

z^{2} + 9 = 0

Move

9

to the right side

z^{2} = - 9

For

x^{2} = f (a)

the solutions are

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

z = - 9, z = - - 9

- 9 = 3 i

- - 9 = - 3 i

z = 3 i, z = - 3 i

135 = (2 x + 3) (2 x - 3)

9 x^{2} - 3 x = 0

2 x^{2} - x - 3 = 0

y^{2} + y - 20 = 0

5 b^{2} + 3 b - 4 = 0
