Limit x→∞  { [√(x2 - 2x + 3)] - (x + 4) } = permisi ini apaya jawabanya

Bab Limit
Matematika SMA Kelas XI

Lim ((√(x² - 2x + 3)) - (x + 4))
x→~

= Lim ((√(x² - 2x + 3)) - √(x + 4)²)
...x→~

= Lim ((√(x² - 2x + 3)) - √(x² + 8x + 16))
...x→~

a = 1; b = -2; c = 3
p = 1; q = 8; r = 16

karena a = p, maka
(b - q)/(2√a)
= (-2 - 8)/(2√1)
= -10/2
= -5
