lim x -> tak terhingga (2x +1 ) - akar 4x^2 - 4x - 3 =

Lim (2x+1) - √(4x²-4x-3)
x→~

Lim √(4x²+4x+1)- √(4x²-4x-3)
x→~

b-q / 2√a
4-(-4) / 2√4
8/2.2
8/4
2
jadi hasilnya 2

Lim
x -> tak terhingga (2x +1 ) - akar 4x^2 - 4x - 3 =
=(2× + 1 )^2 - (akar 4×^2 -4× -3)^2
=(4×^2 + 2× + 2× + 1) - (4×^2 -4× - 3)
=(4×^2 + 4× +1 - 4×^2 +4× + 3)÷×^2
=0
