Lim x->1 √x²+3 - x-1 / 1-x² Hasil apa ya kak Tolong di bantu Makasih

Lim √x²+3 - x-1 / 1-x²
x→1

Lim √x²+3 -(x+1)/ 1-x² kali √x²+3 +(x+1) / √x²+3 +(x+1)
x→1

Lim (x²+3) - (x+1)² / (1-x²)(√x²+3 + (x+1))
x→1

Lim (x²+3) - (x²+2x+1) / (1-x²)(√x²+3 + (x+1))
x→1

Lim -2x+2 / -(x²-1)√x²+3 +(x+1))
x→1

Lim -2(x-1)/ -(x+1)(x-1))√x²+3 +(x+1))
x→1

Lim 2/ (x+1)√x²+3 +(x+1))
x→1

2 / (1+1)√(1²+3)+(1+1)
2 / 2√4 + 2
2 / 8
¼

jadi hasilnya ¼
