Algebra II Seeing Structure in Expressions


Seeing Structure in Expressions


Interpret the structure of expressions. [Polynomial and rational]
HSA-SSE.A.1. Interpret expressions that represent a quantity in terms of its context. tools-icon
a. Interpret parts of an expression, such as terms, factors, and coefficients.  tools-icon
b. Interpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret P(1 + r)n as the product of P and a factor not depending on P.  tools-icon
HSA-SSE.A.2. Use the structure of an expression to identify ways to rewrite it. For example, see x4 – y4 as (x2)2 – (y2)2, thus recognizing it as a difference of squares that can be factored as (x2 – y2)(x2 + y2). tools-icon
Write expressions in equivalent forms to solve problems.
HSA-SSE.B.4. Derive the formula for the sum of a finite geometric series (when the common ratio is not 1), and use the formula to solve
problems. For example, calculate mortgage payments.
