Lim x-tak terhingga (2x-5-akar 4x kuadrat -10x + 5)

Kelas 11 Matematika
Bab Limit

Lim (2x - 5 - √(4x² - 10x + 5))
x→∞

= lim (√(2x - 5)² - √(4x² - 10x + 5))
   x→∞

= lim (√(4x² - 20x + 25) - √(4x² - 10x + 5))
   x→∞

a = 4; b = -20; c = 25; p = 4; q = -10; r = 5

Karena a = p = 2, maka

(b - q)/(2√a)
= (-20 - (-10))/(2 . √4)
= (-20 +10) / (2 . 2)
= -10/4
= -5/2
= -2.5
