= 6x / (x-3) (x+3) - x / (x-3)
disamakan penyebutnya
= 6x (x-3)(x+3) - x(x+3) / (x-3)(x+3)
= 6x - x^2 + 3x / (x-3)(x+3)
= -x^2 + 9 / (x-3)(x+3)
= (-x+3)(x+3) / (x-3)(x+3)
= (-x+3 ) / (x-3)
= 6x / (x-3) (x+3) - x / (x-3)
Penyebutnya kemudian di smakan :
= 6x (x-3)(x+3) - x(x+3) / (x-3)(x+3)
= 6x - x^2 + 3x / (x-3)(x+3)
= -x^2 + 9 / (x-3)(x+3)
= (-x+3)(x+3) / (x-3)(x+3)
= (-x+3 ) / (x-3)
Maka dapatlah hasilnya yaitu : ( -×+3 ) Atau ( ×-3 )
Maaf kalau salah
