1. Lim x -> 4 x² - 2x - 8 / √x - 2 2. Lim x-> 0 x² / 1-√1+x² Tolong dibantu ya soalnya mau dikumpul pakai Cara nya ya

1.
(x² - 2x - 8) / (√x - 2)
= (x - 4)(x + 2) / (√x - 2) × (√x + 2) / (√x + 2)
= (x - 4)(x + 2)(√x + 2) / (x - 4)
= (x + 2)(√x + 2)
= (4 + 2)(√4 + 2)
= 6(2 + 2)
= 6 × 4
= 24

2.
x² / (1 - √(1 + x²))
= x² / (1 - √(1 + x²)) × (1 + √(1 + x²)) / (1 + √(1 + x²))
= x²(1 + √(1 + x²)) / (1 - (1 + x²))
= x²(1 + √(1 + x²)) / -x²
= -(1 + √(1 + x²))
= -(1 + √(1 + 0))
= -(1 + √1)
= -(1 + 1)
= -2
