Pertidaksamaan2x² - x - 3 ≥ 0
(2x -3)(x + 1) ≥ 0
x ≥ 3/2 atau x ≤ -1
6x² + x - 2 > 0
(3x + 2)(2 x - 1) > 0
x < -2/3 atau x > 1/2
Verified answer
1) 2x² - x - 3x ≥ 0(x + 1)(2x - 3) = 0
x = -1 atau x = 3/2
HP = {x ≤ -1 atau x ≥ 3/2}
2) 6x² + x - 2 > 0
(3x + 2)(2x - 1) = 0
x = -2/3 atau x = 1/2
HP = {x ≤ -2/3 atau x ≥ 1/2}
