## Study Notes

### Algebra II Module 3 Concepts

• Expression: A combination of constants, variables, or coefficients without an equality sign.
• Term: The basic building block comprising a constant, variable, or coefficients paired with variables, separated by addition or subtraction.
• Polynomial Arrangement: Terms arranged in descending order based on the exponent of each term.
• Degree of Polynomials: The highest exponent value in a polynomial; e.g., ( g^4 - 16g^3 ) has a degree of 4, whereas ( x^3y^2 + 9x^2y ) has a degree of 5 (3 + 2).
• Monomial: An expression consisting of a single term, such as ( 3p ).
• Binomial: An expression with exactly two terms, for instance, ( 3p + 2x^2 ).
• Trinomial: An expression that has three terms, like ( 3p + 2x^2 - 2xy ).
• Polynomial: An expression with four or more terms, such as ( 3p + 2x^2 - 2xy - 5x^2 ).
• Adding Polynomials: Requires distributing any coefficients and combining "like terms" with identical exponents.
• Subtracting Polynomials: Similar to addition, but includes distributing a negative sign across the polynomial being subtracted.
• Distributive Property: When multiplying, distribute the factor to each term inside parentheses, including exponents.
• Multiplying Binomials (FOIL): Use the First, Outside, Inside, and Last method for multiplying binomials.
• Greatest Common Factors (GCF): The largest factor shared by all terms, useful for simplifying expressions.
• Difference of Squares Binomial: A binomial ( a^2 - b^2 ) that factors into ( (a + b)(a - b) ).
• Perfect Square Trinomial: A trinomial ( a^2 + 2ab + b^2 ) that factors into ( (a + b)^2 ) or ( a^2 - 2ab + b^2 ) that factors into ( (a - b)^2 ).
• Factoring Trinomials: Involves factoring out the GCF, determining binomial factors, and verifying results via FOIL.
• Factoring by Grouping (Four-Term Polynomials): Factor out the GCF, group terms, factor the GCF from groups, factor the common binomial, and check via FOIL.
• Perfect Cube: A three-dimensional shape with equal length, width, and height, where volume equals the cube of one dimension.
• Difference of Cubes: The polynomial ( a^3 - b^3 ) can be factored as ( (a - b)(a^2 + ab + b^2) ).
• Sum of Cubes: The polynomial ( a^3 + b^3 ) can be factored as ( (a + b)(a^2 - ab + b^2) ).
• Expanding Binomials (Pascal's Triangle): Identify coefficients and substitute components step-by-step to expand binomials correctly.
