Polynominals
by Jessi Bee
1. Definitions
1.1. Term - an expression formed from the product of numbers and/or variables.
1.2. Variables - a letter used to represent an unknown number
1.3. Coefficient - a non-changing variable
1.4. Degree - the sum of exponents on the variables
1.5. Polynominal - an expression where there is a sum of terms each of which is the product of a constant and one or more variables
2. Factoring
2.1. 16x2y – 24xy3 + 8xy = (8xy)(2x – 3y2 + 1)
2.2. Simplifying expressions to their most factored forms
2.3. New node
3. Algebra Tiles
3.1. Using a model of math tiles to solve an equation
3.2. Using tiles
4. Greatest Common Factor/ Multiples
4.1. 12 = 3 x 4 = 3 x 2 x 2 = 3 x 2^2
4.2. 18 = 3 x 6 = 3 x 3 x 2 = 3^2 x 2
4.3. Factoring
4.4. 4 = 4, 8, 12, 16, 24, 28, 32...
4.5. 6 = 6, 12...
5. Example Multiplication of Polynomials
5.1. 2(x+1)
5.2. x(x-3) + 4(2+x)
5.3. (x^2+1)(x+3)
5.4. x^2 + 5(x^2-2x+1)

7. Multiplication
7.1. 2y x 3y = 6y^2
7.2. (x+1)(x-1) = x^2-1
