A.SSE.A.1: MODELING EXPRESSIONS
Interpret expressions that represent a quantity in terms of its context. a. Write the standard form of a given polynomial and identify the terms, coefficients, degree, leading coefficient, and constant term. b. Interpret expressions by viewing one or more of their parts as a single entity. e.g., interpret P(1+r)n as the product of P and a factor not depending on P. This standard is a fluency recommendation. Fluency in transforming expressions and chunking (seeing parts of an expression as a single object) is essential in factoring, completing the square, and other mindful algebraic calculations.
Key Concepts and Vocabulary
Degree: The degree of a polynomial is determined by the highest exponent of the variable within the polynomial.
Leading Coefficient: The leading coefficient is the number that multiplies the term with the highest degree.
Constant Term: This is the term that does not have a variable associated with it.
Example: 3x² + 5x - 2 is in standard form (highest degree term first, then decreasing).
