Solution

Given it has extremum values at x=1 and x=2
⇒f′(1)=0  and  f′(2)=0
Given f(x) is a fourth degree polynomial 
Let  f(x)=ax4+bx3+cx2+dx+e
Given 
limx0[1+f(x)x2]=3
limx0[1+ax4+bx3+cx2+dx+ex2]=3
limx0[1+ax2+bx+c+dx+ex2]=3
For limit to have finite value, value of 'd' and 'e' must be 0
⇒d=0  & e=0
Substituting x=0 in limit 
⇒ c+1=3
⇒ c=2
f(x)=4ax3+3bx2+2cx+d
x=1 and x=2 are extreme values,
f(1)=0 and $f^{\prime}(2)=0
4a+3b+4=0 and 32a+12b+8=0 
By solving these equations
we get, a=12 and b=2
So,
f(x)=x422x3+2x2
f(x)=x2(x222x+2)
f(2)=22(24+2)
f(2)=0
