Nilai lim x = tak terhingga akar 9xkuadrat - 6x + 8 - (3x+2)

Kelas 11 Matematika
Bab Limit

Lim (√(9x² - 6x + 8) - (3x + 2))
x→∞

= Lim (√(9x² - 6x + 8) - √(9x² + 12x + 4)
   x→∞

a = 9; b = -6; c = 8; p = 9; q = 12; r = 4

Karena a = p = 9, maka

(b - q)/(2 √a)
= (-6 - 12) / (2 . √9)
= -18/(2 . 3)
= -18/6
= -3
