5/(×+3)+7/(×-3)(×+3)= brp hasilnya

Jawaban:

$frac{5x - 8}{x^{2} - 9}$

Penjelasan dengan langkah-langkah:

$frac{5}{(x + 3)} + frac{7}{(x - 3)(x + 3)} \ = frac{5(x - 3)}{(x + 3)(x - 3)} + frac{7}{(x - 3)(x + 3)} \ = frac{5x - 15 + 7}{(x + 3)(x - 3)} \ = frac{5x - 8}{ {x}^{2} - 9}$

Jawaban:

= (5x-8)/(x²-9)

Penjelasan dengan langkah-langkah:

5/(x+3) + 7/(x-3)(x+3)

= 5.(x-3)/(x+3)(x-3) + 7/(x-3)(x+3)

= (5x-15)/(x-3)(x+3) + 7/(x-3)(x+3)

= (5x-15+7)/(x-3)(x+3)

= (5x-8)/(x-3)(x+3)

= (5x-8)/(x²-9)
