Jawaban:

B. ( – 4,0 ) dan (2, 0)

Penjelasan dengan langkah-langkah:

$f(x) = 0 \ f(x) = {x}^{2} + 2x - 8 \ 0 = {x}^{2} + 2x - 8 \ {x}^{2} + 2x - 8 = 0 \ {x}^{2} + 4x - 2x - 8 = 0 \ x(x + 4) - 2(x + 4) = 0 \ (x + 4)(x - 2) = 0 \ x = - 4 \ x = 2$

Maka, ( – 4,0 ) dan (2, 0)

maaf kalau salah

semoga membantu
