Question

Ada yang bisa bantu?

Answer 1

Lim √(4x^2 + 4x - 3) - (2x - 5)
= Lim √(4x^2 + 4x - 3) - √(2x - 5)^2
= Lim √(4x^2 + 4x - 3) - √(4x^2 - 20x + 25)
a = 4, b = 4, c = -3, p = 4, q = -20, r = 25
Karena a = p maka nilai limitnya
(b - q)/2√a = (4 - (-20))/2√4 = 24/4 = 6

Answer 2

Lim (√4x²+4x-3 - (2x-5))
lim (√4x²+4x-3 - (√(2x-5)²))
lim (√4x² +4x-3 -√4x² -20x+25)

a = 4. ; b= 4 ; c=-3
p = -20 ; q = 25

b-p /2√a
=4-(-20) /2√4
=24/2.2
=24/4
= 6

semoga membantu
