lim x-∞ √4xkuadrat +2 - (2x -3) tlg bantuan nya

Kelas 11 Matematika
Bab Limit

lim (√(4x² + 2) - (2x - 3))
x→∞

= lim (√(4x² + 2) - √(2x - 3)²)
   x→∞

= lim (√(4x² + 2) - √(4x² - 12x + 9))
   x→∞

a = 4; b = 0; c = 2; p = 4; q = -12; r = 9

Karena a = p = 4, maka

(b - q)/(2 √a)
= (0 - (-12)) / (2√4)
= 12/(2 . 2)
= 3
