получается делаем так:

сначала решаем уравнение как и обычно т.е. теоремой виетта или дискриминантом

х^2-4х+3=0

я решу теоремой виетта:

сумма корней равна 4

произведение 3

значит корни 1 и 3

далее:

есть такая формула разложение на множетели квадратного уравнения выглядит так:                 a(x-x1)(x-x2), где а-множетель перед квадратом в нашем случае это 1, х1 и х2 - корни. 

подставим в неё наши корни, получим  (x-1)(x-3)=0

так а теперь решим это неравенство  (x-1)(x-3)> 0

методом интегралов ( тут 3 промежутка от минус бесконечности до 1 от 1 до 3 и от 3 до плюс бесконечности):

допустим х =0, подставим (0-1)(0-3)=3 знак + значит в промежутке от минус бесконечности до 1 знак + 

от 1 до 3 знак -

от 3 до плюс бесконечности +

ответ: х принадлежит промежутку  от минус бесконечности до 1 и  от 3 до плюс бесконечности

The coronavirus, firstly, allowed me to devote more time to my beloved family, and secondly, because of the desperate situation, I got used to cooking at home. I realized how many unnecessary things we use, from clothes to household appliances. All this can be minimized and our life will not become worse from this. We live in the age of consumption, and being isolated, you are thinking more and more about environmental pollution. Taking out the trash, I think more and more about the consumption of plastic and cellophane.

Of course, the pandemic exposed all the problems of our country in the field of health care, education and indicated gaps in work. In my opinion, we have lost spirituality and stopped caring about people close to us. I wish that after the end of COVID-2019, people's attitudes towards life - towards themselves, health and the planet will change. "
