I would encourage you to test your solutions by substituting for x and checking whether LHS resolves to 3. It will do for your real solutions but not zero and I doubt the complex solutions do either.
You have too many trivial and redundant steps. You can skip many of them because the students who watch your video are at least middle-high school levels and already no those steps. Dr. Ajit Thakur (USA).

Так, если х=0, то уравнение не будет решаться правильно
То есть
В числители будет 0 и в знаменатели будет 0
То есть будет 0÷0=3
Но это ж неправильно
我也同樣看法
同樣的x2+x+1也不能是0
這樣也是0÷0=3
所以答案只有2+√3,2-√3
you must write x must be different from zero
asnwer=0 isit
