Polynominals da Mind Map: Polynominals

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. Multiplication

2.1. 2y x 3y = 6y^2

2.2. (x+1)(x-1) = x^2-1

2.3. x(x^2+2x+1) = x^3+2x^2+x

2.4. Multiplying using tiles

2.5. (x2 + 2x + 3)(2x2 – 3x + 1) = 2x4 + x3 + x2 – 7x + 3

2.6. Multiply the expressions together

3. Factoring

3.1. 16x2y – 24xy3 + 8xy = (8xy)(2x – 3y2 + 1)

3.2. Simplifying expressions to their most factored forms

3.3. New node

4. Nomials

4.1. Monomials - an expression with only one term

4.2. Binomials - an expression with two terms

4.3. Trinomials - an expression with three terms

4.4. Polynomials - an expression with four or more terms

5. Algebraically

5.1. To solve an expression using mathematical terms such as with numbers and signs.
