hasil dari 4/x+3 +5/x-2 adalah a.9/(x+3)(x+2) b.20/(x+3)(x-2) c.9x+1/(x+3)(x-2) d.9x + 7/ (x+3)(x-25)

jawab

4.(x+3) + 5/(x-2) =

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

= ( 4x -8 + 5x + 15)/(x+3)( x-2)

=(9x + 7)// (x + 3)(x - 2)

4(x-2)/(x+3)(x-2)+5(x+3)/(x+3)(x-2)=
4(x-2)+5(x+3)/(x+3)(x-2)=
(4x-8)+(5x+15)/(x+3)(x-2)=
9x+7/(x+3)(x-2).
jawabannya 9x+7/(x+3)(x-2)

semoga membantu :)
