№307 (с. 103)
Условие. №307 (с. 103)
Решение 8. №307 (с. 103)
Исходное уравнение: $(x^2 + 8x)^2 - 4(x + 4)^2 = 256$.
Заметим, что выражение во второй скобке связано с выражением в первой. Раскроем квадрат второго слагаемого: $(x + 4)^2 = x^2 + 2 \cdot x \cdot 4 + 4^2 = x^2 + 8x + 16$.
Подставим это в уравнение:
$(x^2 + 8x)^2 - 4(x^2 + 8x + 16) = 256$.
Теперь очевидна замена переменной. Введем новую переменную $t = x^2 + 8x$.
Уравнение принимает вид:
$t^2 - 4(t + 16) = 256$
Решим это уравнение относительно $t$:
$t^2 - 4t - 64 = 256$
$t^2 - 4t - 64 - 256 = 0$
$t^2 - 4t - 320 = 0$
Это квадратное уравнение. Найдем его корни через дискриминант.
$D = b^2 - 4ac = (-4)^2 - 4 \cdot 1 \cdot (-320) = 16 + 1280 = 1296$.
$\sqrt{D} = \sqrt{1296} = 36$.
Корни для $t$:
$t_1 = \frac{-(-4) + 36}{2 \cdot 1} = \frac{4 + 36}{2} = \frac{40}{2} = 20$.
$t_2 = \frac{-(-4) - 36}{2 \cdot 1} = \frac{4 - 36}{2} = \frac{-32}{2} = -16$.
Теперь выполним обратную замену для каждого найденного значения $t$.
1. При $t = 20$:
$x^2 + 8x = 20$
$x^2 + 8x - 20 = 0$
Найдем дискриминант: $D_1 = 8^2 - 4 \cdot 1 \cdot (-20) = 64 + 80 = 144 = 12^2$.
$x_1 = \frac{-8 - 12}{2} = \frac{-20}{2} = -10$.
$x_2 = \frac{-8 + 12}{2} = \frac{4}{2} = 2$.
2. При $t = -16$:
$x^2 + 8x = -16$
$x^2 + 8x + 16 = 0$
Это формула квадрата суммы: $(x + 4)^2 = 0$.
$x + 4 = 0$, откуда $x_3 = -4$.
Ответ: $-10; -4; 2$.
б)Исходное уравнение: $2(x^2 - 6x)^2 - 120(x - 3)^2 = 8$.
Для удобства разделим все члены уравнения на 2:
$(x^2 - 6x)^2 - 60(x - 3)^2 = 4$.
Как и в предыдущем пункте, раскроем квадрат: $(x - 3)^2 = x^2 - 6x + 9$.
Подставим это выражение в уравнение:
$(x^2 - 6x)^2 - 60(x^2 - 6x + 9) = 4$.
Введем новую переменную $t = x^2 - 6x$.
Уравнение примет вид:
$t^2 - 60(t + 9) = 4$
Решим полученное уравнение относительно $t$:
$t^2 - 60t - 540 = 4$
$t^2 - 60t - 544 = 0$
Найдем дискриминант: $D = b^2 - 4ac = (-60)^2 - 4 \cdot 1 \cdot (-544) = 3600 + 2176 = 5776$.
$\sqrt{D} = \sqrt{5776} = 76$.
Корни для $t$:
$t_1 = \frac{-(-60) + 76}{2 \cdot 1} = \frac{60 + 76}{2} = \frac{136}{2} = 68$.
$t_2 = \frac{-(-60) - 76}{2 \cdot 1} = \frac{60 - 76}{2} = \frac{-16}{2} = -8$.
Выполним обратную замену.
1. При $t = 68$:
$x^2 - 6x = 68$
$x^2 - 6x - 68 = 0$
Найдем дискриминант: $D_1 = (-6)^2 - 4 \cdot 1 \cdot (-68) = 36 + 272 = 308$.
$\sqrt{D_1} = \sqrt{308} = \sqrt{4 \cdot 77} = 2\sqrt{77}$.
$x_{1,2} = \frac{-(-6) \pm 2\sqrt{77}}{2} = \frac{6 \pm 2\sqrt{77}}{2} = 3 \pm \sqrt{77}$.
2. При $t = -8$:
$x^2 - 6x = -8$
$x^2 - 6x + 8 = 0$
По теореме Виета, сумма корней равна 6, а произведение равно 8. Следовательно, корни $x_3 = 2$ и $x_4 = 4$.
Ответ: $3 - \sqrt{77}; 2; 4; 3 + \sqrt{77}$.
