Tolong di bantu ya :)

Lim (4 – x^2) / (3 – V(4x+1)
= lim (4 – x^2)(3+V(4x+1) / (3-V(4x+1)(3+V(4x+1)
= lim (4-x^2)(3+V(4x+1) / { 3^2 – (4x+1) }
= lim (2-x)(2+x)(3+V(4x+1) / (9-4x-1)
= lim (2-x)(2+x)(3+V(4x+1)) / -4x +8
= lim (2-x)(2+x)(3+V(4x+1)) / 4(-x+2)
= lim (2-x)(2+x)(3+V(4x+1)) / 4(2-x)
= lim (2+x)(3+V(4x+1)) /4
= (2+2)(3+V(4.2 + 1 ) / 4
= (4)(3+V9) / 4
= 3 +V9
= 3 + 3
= 6
