Soal mat. Tolong bantu ya. Thanks.

(8x^2 - 3x + 10)/(5x - 2) ≤ 2x - 1
(8x^2 - 3x + 10)/(5x - 2) + 1 - 2x ≤ 0
(8x^2 - 3x + 10 + (1 - 2x)(5x - 2))/(5x - 2) ≤ 0
(8x^2 - 3x + 10 + 5x - 2 - 10x^2 + 4x)/(5x - 2) ≤ 0
(-2x^2 + 6x + 8)/(5x - 2) ≤ 0
-2(x^2 - 3x - 4)/(5x - 2) ≤ 0
-2(x - 4)(x + 1)/(5x - 2) ≤ 0
x = 4 atau x = -1 atau x = 2/5
+++ [-1] --- (2/5) +++ [4] ----
-1 ≤ x < 2/5 atau x ≥ 4
