x^{2} = - 9

x = 3 i, x = - 3 i

Solution steps

x^{2} = - 9

Move

9

to the left side

x^{2} + 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 0 \pm 0 ^{2} - 4 \cdot 1 \cdot 9}{2 \cdot 1}

Simplify

0^{2} - 4 \cdot 1 \cdot 9 : 6 i

x_{1, 2} = \frac{- 0 \pm 6 i}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 0 + 6 i}{2 \cdot 1}, x_{2} = \frac{- 0 - 6 i}{2 \cdot 1}

x = \frac{- 0 + 6 i}{2 \cdot 1} : 3 i

x = \frac{- 0 - 6 i}{2 \cdot 1} : - 3 i

The solutions to the quadratic equation are:

x = 3 i, x = - 3 i
