4x-2x^2+4x^3 from 4x^3+x-3x^2





   arrange your expressions :



    4x^3 - 2x^2 + 4x 

  -(4x^3 - 3x^2 + x)   Since we are subtracting we will change the sign of the 

____________________   subtrahend





   4x^3 - 2x^2 + 4x 

  -4x^3 + 3x^2 - x   Now we are ready to combine like terms

   0    + x^2 + 3x    



 answer is x^2 + 3x
