新GRE数学要点:Subtracting Polynomials

 Subtracting Polynomials   To subtract polynomial from another, subtract the like terms. Like terms are those with the same variable and identical power.
  Example:
  By subtracting (3x+2) from (4x2-x+2),we get 4x2+(-1-3)x+(2-2)=4x2-4x.
  Remember:
  Only subtract the like terms.
