tolong dijawab secepatnya ya... no 1 sampai 5 pakai caranya terima kasih .....

1) (3x+2 / 4) + (4x-5 / 3)
= 3(3x + 2) + 4(4x - 5)
--------------------------------
( 4 ) ( 3 )
= 9x + 6 + 16x - 20
-----------------------------
12
= 25x - 14
---------------
12

2) (4 / x+2 ) + ( 5 / x+3 )
= 4(x + 3) + 5(x + 2)
-----------------------------
( x + 2) ( x + 3)
= 4x + 12 + 5x + 10
----------------------------
( x + 2)(x + 3)
= 9x + 22
----------------
x² + 5x + 6

3) ( 2 / x-4 ) + ( 3 / x+3 )
= 2(x + 3) + 3(x - 4)
-----------------------------
( x - 4 ) ( x + 3)
= 2x + 6 + 3x - 12
-------------------------
x² - 4x + 3x - 12
= 5x - 6
---------------
x² - x - 12

4) ( 5 / x-5 ) + ( 6 / x-6 )
= 5 (x - 6) + 6 (x - 5)
------------------------------
( x - 5 ) ( x - 6 )
= 5x - 30 + 6x - 30
----------------------------
x² - 5x - 6x + 30
= 11x - 60
---------------
x² - 11x + 30

5) ( 7 / x+2) + ( 8 / (x+2)(x+3) )
= 7(x + 3) + 8
-------------------
( x + 2)(x + 3)
= 7x + 21 + 8
--------------------
x² + 2x + 3x + 6
= 7x + 29
------------------
x² + 5x + 6
