Для решения квадратного уравнения можно воспользоваться двумя основными методами: через дискриминант или с помощью теоремы Виета. Метод 1: Через дискриминант Уравнение имеет вид , где:
1. Находим дискриминант по формуле : Так как , уравнение имеет два различных вещественных корня. 2. Находим корни по формуле :
- Первый корень ( ):
Второй корень ( ):
Метод 2: Теорема Виета Для приведенного квадратного уравнения (где ) справедливы следующие равенства:
Подберем числа, которые в произведении дают 48, а в сумме 14:
- Пары множителей 48: (2 и 24), (3 и 16), (4 и 12), (6 и 8).
- Проверка суммы: .
Следовательно, корни уравнения: 6 и 8. Ответ: . Хотите, чтобы я решил другое уравнение или разобрал систему уравнений?
