if a car moving at a constant rate travel (2x³-x²-4x+3)km in (x²-2x+1) hours what is the rate of the car in km per hour?
I need it asap thanks

  1. so divide
    2x^3-x^2-4x+3
    ---------------------
    x^2-2x+1

  3. check:
    (2x+3)(x^2-2x+1)
    is
    2x(x^2-2x+1)
    +
    3(x^2-2x+1)
    which is
    2 x^3 -4x^2 +2x + 3x^2 -6x+3
    = 2x^3 - x^2 - 4x +3
    remarkable !
