• on simplyfying the above equations..................
  we get,
  (ax2+bx+5)/2 = (2bx2+6x+a-2)/6
  
  on comparing the both the equations we get ....
  3a=2b, 3b=6
  hence
  b=2, a=4/3 ;

• put x=1 in both equations and solve the both equations

• f(x)= ax^2+bx+6/2x=0 .................(i)
  F(x)=2bx^2+6x+a/3x-3=0 ..............(ii)
  in both...(i) & (ii) put x=1 we get
  a+b=-3 .......(iii)
  a+6b=-9 .......(iv)
  solving these (iii) & (iv) we get a=-9/5 , b=-6/5
