Ответ:
Firstly, add 2 to both sides of the equation:![\frac{3}{5}x^2=-3](/tpl/images/0077/7893/45edf.png)
Next, multiply both sides by 5/3:![x^2=-5](/tpl/images/0077/7893/ecef0.png)
Next, square root both sides:![x= \pm \sqrt{-5}](/tpl/images/0077/7893/9e40b.png)
Lastly, factor out i (i = √-1) and your answer will be![x= \pm \sqrt{5}i](/tpl/images/0077/7893/378df.png)
