dibantu yaa cuma 2 soal pake cara yaa makasih

( 4 / 2x-5 ) - ( 3 / 3x+1 )

= 4 ( 3x + 1 ) - 3 ( 2x - 5 )
-------------------------------------
( 2x - 5 )( 3x + 1 )

= 12x + 4 - 6x + 15
----------------------------
6x² - 15x + 2x - 5

= 6x + 19
-----------------
6x² - 13x - 5


f(x) = 8 - 2x
f(-2) = 8 - 2(-2) = 8 + 4 = 12
f(-1) = 8 - 2(-1) = 8 + 2 = 10
f(0) = 8 - 0 = 8
f(1) = 8 - 2(1) = 8 - 2 = 6
f(2) = 8 - 2(2) = 8 - 4 = 4
hp = { x | 5 < x < 13 , x € A }
