Решение 8. №131 (с. 49)
Чтобы определить количество корней квадратного трёхчлена вида $ax^2 + bx + c$, необходимо найти его дискриминант по формуле $D = b^2 - 4ac$.
- Если $D > 0$, трёхчлен имеет два различных действительных корня.
- Если $D = 0$, трёхчлен имеет один действительный корень (или два совпадающих корня).
- Если $D < 0$, трёхчлен не имеет действительных корней.
а) Для трёхчлена $3x^2 - 8x + 2$ коэффициенты равны: $a = 3$, $b = -8$, $c = 2$.
Вычислим дискриминант:
$D = b^2 - 4ac = (-8)^2 - 4 \cdot 3 \cdot 2 = 64 - 24 = 40$.
Так как $D = 40 > 0$, квадратный трёхчлен имеет два различных корня.
Ответ: 2 корня.
б) Для трёхчлена $-\frac{1}{2}y^2 + 6y - 18$ коэффициенты равны: $a = -\frac{1}{2}$, $b = 6$, $c = -18$.
Вычислим дискриминант:
$D = b^2 - 4ac = 6^2 - 4 \cdot (-\frac{1}{2}) \cdot (-18) = 36 - 2 \cdot 18 = 36 - 36 = 0$.
Так как $D = 0$, квадратный трёхчлен имеет один корень.
Ответ: 1 корень.
в) Для трёхчлена $m^2 - 3m + 3$ коэффициенты равны: $a = 1$, $b = -3$, $c = 3$.
Вычислим дискриминант:
$D = b^2 - 4ac = (-3)^2 - 4 \cdot 1 \cdot 3 = 9 - 12 = -3$.
Так как $D = -3 < 0$, квадратный трёхчлен не имеет действительных корней.
Ответ: нет корней.
