Bantu jawab matematika ​

Jawaban:

Lim (x² – 2x – 15) / (x – 5)

x –> 5

= (x² – 2x – 15) / (x – 5)

= (x – 5)(x + 3) / (x – 5)

= (x + 3)

= (5 + 3)

= 8

Penjelasan dengan langkah-langkah:

Gunakan dalil L'hopital

lim (x^2 – 2x – 15)/(x – 5)

x → 5

lim (2x – 2)/1

x → 5

= 2(5) – 2 / 1

= 8/1

= 8
