Log x2 - log (x + 6) = 0?

Log x2 - log (x + 6) = 0.

En resumen

Log x² - log (x + 6) = 0 Log (x² / (x + 6)) = 0 (x² / (x + 6)) = 10 ^ 0 x² / (x + 6) = 1 x² = x + 6 x² - x - 6 = 0 (x - 3)(x + 2) = 0 x - 3 = 0 x + 2 = 0 x1 = 3 x2 = - 2.

Log x² - log (x + 6) = 0

Log (x² / (x + 6)) = 0

(x² / (x + 6)) = 10 ^ 0

x² / (x + 6) = 1

x² = x + 6

x² - x - 6 = 0

(x - 3)(x + 2) = 0

x - 3 = 0 x + 2 = 0

x1 = 3 x2 = - 2.
