Hasil dari x2-4/x2-2x-8

Kelas 8 Matematika
Bab Aljabar

(x² - 4) / (x² - 2x - 8)
= (x² - 2²) / (x² - 4x + 2x - 8)
= ((x + 2) (x - 2)) / ((x (x - 4) + 2 (x - 4))
= ((x + 2) (x - 2)) / ((x - 4) (x + 2))
= (x - 2) / (x - 4)

[tex] \frac{2x - 4}{2x - 2x -8} [/tex] = [tex] \frac{2x - 4}{-8} = \frac{x - 2}{-4}[/tex]
