Himpunan penyelesaian pertidak sesuaian x²+5x+6<=0

x" + 5x + 6 <= 0
(x + 2)(x + 3) <= 0

x + 2 <= 0
x <= -2

x + 3 <= 0
x <= -3

Maka, x<= 2 atau x <= 3

Semoga membantu dan semoga bermanfaat...

x^2 + 5x + 6 ≤ 0
(x + 2)(x + 3) ≤ 0
x = -2 atau x = -3
Garis bilangan
+++ (-3) --- (-2) +++
-3 ≤ x ≤ -2
