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.
