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

The answer to your question is:

Step-by-step 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

yes ok                                            

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
