Question

lim x → 2 (x^3- 3x^2 + 4)/(x^4-8x^2+16)
plzz fast....

Answer 1

Lim x → 2 (x^3- 3x^2 + 4)/(x^4-8x^2+16)
=Lim x → 2 d/dx(x^3- 3x^2 + 4)/d/dx(x^4-8x^2+16)
=Lim x → 2  3x^2-6x/4x^3-16x
=Lim x → 2  d/dx(3x^2-6x)/d/dx(4x^3-16x)
=Lim x → 2  (6x-6)/(12x^2-16)
=(6*2-6)/(12*4-16)
=12-6/48-16
=6/32
=3/16 ans
