Question

3.4: (x+8) = 1:xпж решите)))))​

Answer 1

Ответ:

-5,2

Пошаговое объяснение:

3,4:(х+8)=1:х

3,4:х+8=1:х

2х=-8+1-3,4

2х=-10,4

х=-10,4:2

х=-5,2

Answer 2

To solve the equation (x + 8) = 1/x, we can follow these steps:

Step 1: Clear the fraction by multiplying both sides of the equation by x: x(x + 8) = 1

Step 2: Expand the left side of the equation: x^2 + 8x = 1

Step 3: Move all terms to one side to form a quadratic equation: x^2 + 8x - 1 = 0

Step 4: Solve the quadratic equation. We can use the quadratic formula: x = (-b ± √(b^2 - 4ac)) / (2a)

In this case, a = 1, b = 8, and c = -1. Plugging these values into the quadratic formula, we get: x = (-8 ± √(8^2 - 4(1)(-1))) / (2(1))

Simplifying further: x = (-8 ± √(64 + 4)) / 2 x = (-8 ± √68) / 2 x = (-8 ± 2√17) / 2 x = -4 ± √17

So the two solutions to the equation are: x = -4 + √17 x = -4 - √17

Please note that these are the exact solutions. If you need a decimal approximation, you can calculate it using a calculator.
