"решите уравнение\n(х+5) ²-(х-1) ²=48"

(х+5)² - (х-1)² = 48

Let's expand the expressions:

(х+5)² - (х-1)² = (х+5)(х+5) - (х-1)(х-1) = х² + 10х + 25 - (х² - 2х + 1) = х² + 10х + 25 - х² + 2х - 1 = 12х + 24

So, the equation simplifies to:

12х + 24 = 48

Now we can solve for х:

12х = 48 - 24 12х = 24

х = 24 / 12 х = 2

Ответ: значение х равно 2.
