x < 0
jadi x itu harus bilangan minus
(6-2x)² ≥ 7²
36-24x+4x² ≥ 49
4x²-24x+36-49 ≥ 0
4x²-24x-13 ≥ 0
(2x+1)(x-13) ≥ 0
2x+1 = 0 x-13 = 0
2x = -1 atau x = 13
x = -1/2
-> garis bilangan
++++++ - - - - - - - ++++++ uji x = 0 maka hasilnya bil negatif
-1/2 13
himpunan penyelesaiannya adlh {x | x ≤ -1/2 atau x ≥ 13 }
semoga membantu ya :)
