carilah himpunan penyelesaian dr persamaan berikut ini log (xpangkat2 +3x +2) = log (x+1) + log5

log (x² + 3x + 2) = log (x + 1) + log 5
log (x² + 3x + 2) = log 5(x + 1)
log (x² + 3x + 2) = log (5x + 5)
x² + 3x + 2 = 5x + 5
x² + 3x - 5x + 2 - 5 = 0
x² - 2x - 3 = 0
(x - 3)(x + 1) = 0
x = 3    x = -1
