Algebraic Proofs (B) WORKSHEET

Suitable for Grades: Geometry, Algebra II
CCSS: HSA.APR.C.4
CCSS Description: 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.

Algebraic Proofs (B) WORKSHEET DESCRIPTION

This worksheet builds on the work done in Algebraic Proofs (A) by using the basic concepts of writing expressions for even numbers, odd numbers, consecutive numbers, etc, and asking for more complicated sums, differences, and squares to prove statements such as "Prove that the difference between the squares of any two consecutivenumbers is always an odd number" and "prove that the sum of three consecutive numbers is always a multiple of 3". More algebraic proof questions can be found in Algebraic Proofs (C).

All worksheets are created by the team of experienced teachers at Cazoom Math.
