新GRE数学要点: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 (3x+2) and (4x2-x+2),we get (3x+2)(4x2-x+2)=3x(4x2-x+1)+2(4x2-x+2)=12x3-3x2+3x+8x2-2x+4=12x3+(-3+8)x2+(3-2)x+4=12x3+5x2+x+4.
Remember:
Do not froget to multiply all the terms.
Repeat distributive law when multiplying polynomials.
