недопониманиями. Довольно часто у ребят не хватает времени, чтобы детально проработать каждый параграф. Теорию они проходят в спешке, так как основное внимание сосредоточено в основном на практических заданиях, которые учителя задают на дом в больших количествах. ГДЗ «<strong>Алгебра Учебник Макарычев, Миндюк, Нешков 9 класс (Просвещение, 2023г.)</strong>» позволит школьникам сбалансировать учебный процесс, не упуская ни одной мелочи. </p> <p> Многие ученики испытывают проблемы с пониманием таких аспектов: </p> <ol> <li>Действия над действительными числами.</li> <li>Погрешность и точность приближения?</li> <li>Свойства чётности и нечётности функций.</li> <li>Целое уравнение и его корни.</li> <li>Решение неравенств методом интервалов.</li> <li>Уравнение с двумя переменными и его график.</li> </ol> <p> Современные учебники часто снабжены недостаточно развернутой теорией, что мешает учащимся еще раз пробежаться по материалу, если они пропустили урок или не поняли объяснения преподавателя. Поэтому иногда подростки приступают к решению задач так до конца и не разобравшись в параграфах. Неудивительно, что потом в их работах обнаруживается много ошибок. Благодаря решебнику можно избежать любых недочетов при выполнении номеров. </p> <h2> Почему работать с решебником нужно правильно? </h2> <p> Школьники всегда делятся на две категории. Первые, даже с большим скрипом, но находят решения и ответы самостоятельно, а вот вторые постоянно списывают домашние задания и ничего толком в дисциплине не понимают. Но используя <strong>решебник по алгебре за 9 класс к учебнику Макарычева Ю.Н., Миндюка Н.Г., Нешкова К.И.

Довольно часто у ребят не хватает времени, чтобы детально проработать каждый параграф. Теорию они проходят в спешке, так как основное внимание сосредоточено в основном на практических заданиях, которые учителя задают на дом в больших количествах. ГДЗ «<strong>Алгебра Учебник Макарычев, Миндюк, Нешков 9 класс (Просвещение, 2023г.)</strong>» позволит школьникам сбалансировать учебный процесс, не упуская ни одной мелочи. </p> <p> Многие ученики испытывают проблемы с пониманием таких аспектов: </p> <ol> <li>Действия над действительными числами.</li> <li>Погрешность и точность приближения?</li> <li>Свойства чётности и нечётности функций.</li> <li>Целое уравнение и его корни.</li> <li>Решение неравенств методом интервалов.</li> <li>Уравнение с двумя переменными и его график.</li> </ol> <p> Современные учебники часто снабжены недостаточно развернутой теорией, что мешает учащимся еще раз пробежаться по материалу, если они пропустили урок или не поняли объяснения преподавателя. Поэтому иногда подростки приступают к решению задач так до конца и не разобравшись в параграфах. Неудивительно, что потом в их работах обнаруживается много ошибок. Благодаря решебнику можно избежать любых недочетов при выполнении номеров. </p> <h2> Почему работать с решебником нужно правильно? </h2> <p> Школьники всегда делятся на две категории.

№238 (с. 83)
Решение 8. №238 (с. 83)
а)
Дано уравнение:
$$ \frac{1}{x-7} - \frac{1}{x-1} = \frac{1}{x-10} - \frac{1}{x-9} $$
Найдем область допустимых значений (ОДЗ). Знаменатели дробей не должны быть равны нулю:
$x - 7 \neq 0 \Rightarrow x \neq 7$
$x - 1 \neq 0 \Rightarrow x \neq 1$
$x - 10 \neq 0 \Rightarrow x \neq 10$
$x - 9 \neq 0 \Rightarrow x \neq 9$
Таким образом, ОДЗ: $x \in \mathbb{R} \setminus \{1, 7, 9, 10\}$.
Приведем дроби в левой и правой частях уравнения к общему знаменателю.
Левая часть:
$$ \frac{1}{x-7} - \frac{1}{x-1} = \frac{(x-1) - (x-7)}{(x-7)(x-1)} = \frac{x-1-x+7}{x^2-x-7x+7} = \frac{6}{x^2-8x+7} $$
Правая часть:
$$ \frac{1}{x-10} - \frac{1}{x-9} = \frac{(x-9) - (x-10)}{(x-10)(x-9)} = \frac{x-9-x+10}{x^2-9x-10x+90} = \frac{1}{x^2-19x+90} $$
Получаем уравнение:
$$ \frac{6}{x^2-8x+7} = \frac{1}{x^2-19x+90} $$
Используем свойство пропорции (перекрестное умножение), так как знаменатели не равны нулю в ОДЗ:
$$ 6(x^2-19x+90) = 1(x^2-8x+7) $$
Раскроем скобки:
$$ 6x^2 - 114x + 540 = x^2 - 8x + 7 $$
Перенесем все члены в левую часть и приведем подобные слагаемые:
$$ (6x^2 - x^2) + (-114x + 8x) + (540 - 7) = 0 $$
$$ 5x^2 - 106x + 533 = 0 $$
Решим полученное квадратное уравнение. Найдем дискриминант:
$$ D = b^2 - 4ac = (-106)^2 - 4 \cdot 5 \cdot 533 = 11236 - 10660 = 576 $$
$$ \sqrt{D} = \sqrt{576} = 24 $$
Найдем корни уравнения:
$$ x_1 = \frac{-b + \sqrt{D}}{2a} = \frac{106 + 24}{2 \cdot 5} = \frac{130}{10} = 13 $$
$$ x_2 = \frac{-b - \sqrt{D}}{2a} = \frac{106 - 24}{2 \cdot 5} = \frac{82}{10} = 8.2 $$
Оба корня (13 и 8.2) принадлежат ОДЗ.
Ответ: $13; 8.2$.
б)
Дано уравнение:
$$ \frac{1}{x+3} - \frac{1}{x+9} = \frac{1}{x+5} - \frac{1}{x+21} $$
Найдем область допустимых значений (ОДЗ). Знаменатели дробей не должны быть равны нулю:
$x + 3 \neq 0 \Rightarrow x \neq -3$
$x + 9 \neq 0 \Rightarrow x \neq -9$
$x + 5 \neq 0 \Rightarrow x \neq -5$
$x + 21 \neq 0 \Rightarrow x \neq -21$
Таким образом, ОДЗ: $x \in \mathbb{R} \setminus \{-21, -9, -5, -3\}$.
Приведем дроби в левой и правой частях уравнения к общему знаменателю.
Левая часть:
$$ \frac{1}{x+3} - \frac{1}{x+9} = \frac{(x+9) - (x+3)}{(x+3)(x+9)} = \frac{x+9-x-3}{x^2+9x+3x+27} = \frac{6}{x^2+12x+27} $$
Правая часть:
$$ \frac{1}{x+5} - \frac{1}{x+21} = \frac{(x+21) - (x+5)}{(x+5)(x+21)} = \frac{x+21-x-5}{x^2+21x+5x+105} = \frac{16}{x^2+26x+105} $$
Получаем уравнение:
$$ \frac{6}{x^2+12x+27} = \frac{16}{x^2+26x+105} $$
Разделим обе части уравнения на 2:
$$ \frac{3}{x^2+12x+27} = \frac{8}{x^2+26x+105} $$
Используем свойство пропорции:
$$ 3(x^2+26x+105) = 8(x^2+12x+27) $$
Раскроем скобки:
$$ 3x^2 + 78x + 315 = 8x^2 + 96x + 216 $$
Перенесем все члены в правую часть и приведем подобные слагаемые:
$$ 0 = (8x^2 - 3x^2) + (96x - 78x) + (216 - 315) $$
$$ 5x^2 + 18x - 99 = 0 $$
Решим полученное квадратное уравнение. Найдем дискриминант:
$$ D = b^2 - 4ac = 18^2 - 4 \cdot 5 \cdot (-99) = 324 + 1980 = 2304 $$
$$ \sqrt{D} = \sqrt{2304} = 48 $$
Найдем корни уравнения:
$$ x_1 = \frac{-b + \sqrt{D}}{2a} = \frac{-18 + 48}{2 \cdot 5} = \frac{30}{10} = 3 $$
$$ x_2 = \frac{-b - \sqrt{D}}{2a} = \frac{-18 - 48}{2 \cdot 5} = \frac{-66}{10} = -6.6 $$
Оба корня (3 и -6.6) принадлежат ОДЗ.
Ответ: $3; -6.6$.
