Discovery Ed. Lessons 7.3, 9.1 & 9.2

Unit Objectives:

• Classify polynomials, identify key features, and write polynomials in a variety of forms.

• Add, subtract, and multiply polynomials.

• Factor polynomials.

• Rewrite polynomials to reveal the contextual interpretation.

New Jersey Student Learning Standards for this Unit:

• A-SSE.A.1: Interpret expressions that represent a quantity in terms of its context.*

• A-APR.A.1: Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.

• N-RN.A.2: Rewrite expressions involving radicals and rational exponents using the properties of exponents.

• 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.

• A-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).

• A-SSE.B.3a: Factor a quadratic expression to reveal the zeros of the function it defines.
