Masja [62]3 years ago
7 0

Step-by-step explanation:

{x}^{2}  + 25 = 0 \\  \therefore {x}^{2}  =  - 25 \\ \therefore {x}  =  \sqrt{ - 25}  \\  \therefore {x}  =   \pm\sqrt{ - 1 \times 25}  \\ \therefore {x}  = \pm  \sqrt{  25}  \times  \sqrt{ - 1}  \\ \therefore {x}  =  \pm5 \: i  \\ \therefore {x}  = \{ - 5i, \:  \: 5i \} \: \\  is \: the \: solution \: set.
