新gre数学重要考点:Multiplying Polynomials
Multiplying Polynomials
To multiply two polynomials, open up the first polynomial and multiply the second polynomial with each term.
Example:
If we multiply and ,we get =3x+2=12x3-3x2+3x+8x2-2x+4=12x3+x2+x+4=12x3+5x2+x+4.
Remember:
Do not froget to multiply all the terms.
Repeat distributive law when multiplying 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 from ,we get 4x2+x+=4x2-4x.
Remember:
Only subtract the like terms.
