Тест по алгебре: Решение квадратных уравнений через дискриминант (класс 8)

Инструкция: для уравнения ax^2 + bx + c = 0 найдите дискриминант Δ = b^2 - 4ac.

• Если Δ > 0, уравнение имеет два вещественных корня.
• Если Δ = 0, уравнение имеет один вещественный корень.
• Если Δ < 0, вещественных корней нет.

1. Решите квадратное уравнение: x^2 - 5x + 6 = 0. Выберите верный ответ. A) x = 2 и x = 3 B) x = -2 и x = -3 C) x = 1 и x = 6 D) Нет вещественных корней Ответ: A

2. Решите: x^2 - 4x + 4 = 0. A) x = 0 B) x = 2 C) x = -2 D) x = 4 Ответ: B

3. Уравнение: 2x^2 - 3x + 1 = 0. Найдите корни. A) x = 1/2 и x = 1 B) x = 0 и x = 1 C) x = -1 и x = 1 D) x = 2 и x = -1 Ответ: A

4. Уравнение: x^2 + x + 1 = 0. Δ < 0, значит вещественных корней нет. A) x = -1 B) x = 0 C) Нет вещественных корней D) x = 1 Ответ: C

5. Решите: 3x^2 - 2x - 1 = 0. A) x = 1 и x = -1/3 B) x = -1 и x = 1/3 C) x = 2 и x = -1 D) x = 0 и x = -1 Ответ: A
