$3 {x}^{2} - 48 = 0$

$3 {x}^{2} = 48$

${x}^{2} = 16$

$x = + - 4$

Mironov000: это неправильно

Автор ответа: clashofclansoftx

Ответ:

3x²-48=0

переносим -48 в правую часть с противоположным знаком

3x²=48

теперь делим обе части уравнения на 3

x²=16

извлекаем корень из обоих частей уравнения

x=±√16

x=±4
