1. Answer:

   Correct option is

   A

   x3+6×2−20x+8=0

   The given equation is

   f(x)=x3+3×2−5x+1=0

   Replace x by 2x in the above equation to get the desired equation.

   The required equation is

   f(2x)=(2x)3+3(2x)2−5(2x)+1=0

   =8×3+43×2−25x+1=0

   On solving the equation, we get

   x3+6×2−20x+8=0
