Объясните, как решить уравнение х(в квадрате) - 16х = 0
Типа там его делают так: х(х - 16), но как его получили в такой форме?

Первым делом, мы можем вынести за скобки x, потому что х в квадрате и 16х имеют одинаковую букву х. Поэтому мы выносим за скобки х.

Ответ:

x₁ = 0 ; x₂ = 16.

Объяснение:

x² - 16x = 0 ;

x * ( x - 16 ) = 0 ;

x = 0 или х - 16 =  0 ;

                x = 16.
