Ответ:

2(x - 3) + 12x(5 - x) + 12x {}^{2}  \\ x - 6 + 60x - 12x {}^{2}  + 12x {}^{2}  \\ x - 6 + 60x \\ 61x - 6


xNickname: я извиняюсь, у меня получилась ошибка во время решения уравнение, из-за невнимательности, в момент раскрытия скобок. Сейчас напишу, как должно выглядеть правильное уравнение. 2(x-3)+12x(5-x)+12x²=>2x-6+60x-12x²+12x². -12x² и 12x² сокращаются. И получаем уравнение: 2x-6+60x=62x-6
