(x-7)^2 - (x+7)^2 = 32Expanding both squares:(x^2 - 14x + 49) - (x^2 + 14x + 49) = 32x^2 - 14x + 49 - x^2 - 14x - 49 = 32Combining like terms:-28x = 32Divide by -28:x = -32/28x = -8/7
Ответ: x = -8/7
(x-7)^2 - (x+7)^2 = 32
Expanding both squares:
(x^2 - 14x + 49) - (x^2 + 14x + 49) = 32
x^2 - 14x + 49 - x^2 - 14x - 49 = 32
Combining like terms:
-28x = 32
Divide by -28:
x = -32/28
x = -8/7
Ответ: x = -8/7
