Question

Solve the following equations.
ln(x + 2) + ln(x − 2) = ln(−2x − 1)

Answer 1

The answer to your question is:

Explanation:

Data

ln(x + 2) + ln(x − 2) = ln(−2x − 1)

In (x + 2)(x - 2) = In(-2x - 1)

(x + 2)(x - 2) = (-2x - 1)

x² - 4 = -2x - 1

x² + 2x - 4 + 1 = 0

x² + 2x - 3 = 0

(x + 3) (x - 1) = 0

x1 = - 3 x2 = 1
