Eighth-graders Study Polynomials in Algebra
Eighth-graders in Kristina O’Connor’s algebra class fine-tuned their algebra skills by performing operations with polynomials. Polynomials are mathematical expressions of more than two terms, such as 2x-17. “Students have spent much time adding, subtracting, and multiplying polynomials,” O’Connor said. “They are learning the abstract concept of factoring polynomials. They have learned how to factor by grouping, how to factor a difference of perfect squares, and how to factor perfect square trinomials.” Students will learn several other ways to factor polynomials throughout the unit.
