Tolong donk lim x-> (-5) x^2 - 2x -35/ x+5

Materi : Limit fungsi
Kelas : X dan XI

Lim
x → -5 (x² - 2x - 35) / (x+5)
= (Gunakan metode turunan, yaitu :)
= 2x - 2 / 1
= 2(-5) - 2 / 1
= -10 - 2 / 1
= -12 / 1
= -12 → Adalah hasilnya

jawab

limit (x-> -5) (x² -2x -35)/(x + 5)

(i)
limit ( x -> - 5) ( 2x - 2)/(1)
= {2(-5) - 2} / (1)
= -10 - 2
= - 12 


(ii) 
limit (x -> -5) (x²- 2x - 35)/(x + 5)
limit (x -> -5) (x +5)(x - 7)/ (x + 5)
limit (x -> -5) (x - 7)
x= - 5

= - 5 - 7
= - 12
