Strand: ALGEBRA - Arithmetic With Polynomials and Rational Expressions (A.APR)

Perform arithmetic operations on polynomials, extending beyond the quadratic polynomials (Standard A.APR.1). Understand the relationship between zeros and factors of polynomials (Standards A.APR.2–3). Use polynomial identities to solve problems (Standards A.APR.4–5). Rewrite rational expressions (Standards A.APR.6–7).

Standard A.APR.4

Prove polynomial identities and use them to describe numerical relationships. For example, the polynomial identity (x² + y²)² = (x² – y²)² + (2xy)² can be used to generate Pythagorean triples.

• ALGEBRA - Arithmetic With Polynomials and Rational Expressions (A.APR) - Sec Math III Core Guide
  The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for the Secondary Mathematics III - Arithmetic With Polynomials and Rational Expressions (A.APR).
• Introduction to the Materials (Math 3)
  Introduction to the Materials in the Mathematics Three of the The MVP classroom experience begins by confronting students with an engaging task and then invites them to grapple with solving it. As students ideas emerge, take form, and are shared, the teacher orchestrates the student discussions and explorations towards a focused mathematical goal. As conjectures are made and explored, they evolve into mathematical concepts that the community of learners begins to embrace as effective strategies for analyzing and solving problems.
• Trina's Triangles
  This task is a fleshing-out of the example suggested in A-APR.4 of the Common Core document, using the polynomial identity (x2+y2)2=(x2y2)2+(2xy)2 to generate Pythagorean triples.
