# A-sse rewriting a quadratic expression

Make sense of problems and persevere in solving them. Algebra II is a course in which students can learn some technical methods for performing algebraic calculations and transformations, but sense. As the modeling practice is ubiquitous in Algebra II, enhanced by the inclusion of exponential and logarithmic functions as modeling tools Contributing Practice Standards MP. Reason abstractly and quantitatively.  The content standards covered in this unit Seeing Structure in Expressions Interpret expressions that represent a quantity in terms of its context Modeling is best interpreted not as a collection of isolated topics but in relation to other standards.

The star symbol sometimes appears on the heading for a group of standards; in that case, it should be understood to apply to all standards in that group. Use the structure of an expression to identify ways to rewrite it. Modeling is best interpreted not as a collection of isolated topics but in relation to other standards.

For example, if the function h n gives the number of person-hours it takes to assemble n engines in a factory, then the positive integers would be an appropriate domain for the function.

Estimate the rate of change from a graph. For example, given a graph of one quadratic function and an algebraic expression for another, say which has the larger maximum.

Arithmetic with Polynomials and Rational Expressions A. Include equations arising from linear and quadratic functions, and simple rational and exponential functions.

Seeing Structure in Expressions. rutadeltambor.com2 — Use the structure of an expression to identify ways to rewrite it. For example, see x 4 — y 4 as (x²)² — (y²)², thus recognizing it as a difference of squares that can be factored as (x² — y²)(x² + y²).
