1. 2/(x + 3) - 3/(x - 2) 2. ab pangkat 2/c ÷ b/ ac 3. x pangkat 2 + y pangkat 2/x + y x/y + y/x Tolong bantu ya kaka :) Pake cara!!

1) ( 2 / x+3 ) - ( 3 / x-2)
= 2( x - 2) - 3( x + 3)
-----------------------------
( x + 3) ( x - 2)

= 2x - 4 - 3x - 9
------------------------
x² + 3x - 2x - 6

= - x - 13
----------------
x² + x - 6

2) ( ab² / c ) ÷ ( b / ac )
= ( ab²) × ( ac )
----------------------
( c ) × ( b )

= ( b )( ab) × ( a )( c )
-----------------------------
( c ) × ( b )

= ( ab ) × ( a )
= a²b
