if f(x)=x.sq-3x+4 then find the values of x satisfying the eguation f(x)=f(2x+1)

• x=-1 and x= 2/3

• f(x)=x^2-3x+4
  f(2x+1) = (2x+1)^2-3(2x+1)+4
  
  
  f(x)=f(2x+1)
  
  x^2-3x+4 = (2x+1)^2-3(2x+1)+4
  
  solve it to get x= -1 , 2/3

• Given f(x)=x.sq-3x+4 so to get f(2x+1) put x=2x+1 in f(x)
  f(2x+1)=(2x+1).sq-3(2x+1)+4
  =4x.sq-2x+2
  given that f(x)=f(2x+1)
  solve eq and we will get x=-1 and x=2/3
