MULTIPLYING BINOMIALS
USING ALGEBRA
TILES
BINOMIALA mathematical expression consisting of 2 algebraic terms connected by a plus or minus sign.Examples: 2x + 4 , x - 3POLYNOMIAL
A mathematical expression of one or more algebraic terms of which consists of a constant multiplier by one or more variables raise to a non-negative power. Example: 3x2 + 4x + 5 , x3 + 3x2 + x - 8
are manipulative with which you can represent polynomials and perform polynomial operations, such as adding subtracting, multiplying, and dividing.
