Homework Review: Algebraic Expressions and Polynomial Operations

In today's algebra session, we will review our homework on arithmetic with polynomials, including the addition and subtraction of polynomial expressions. We'll use calculators to simplify expressions and verify our solutions. Topics include combining like terms, polynomial multiplication, and factoring. You will work on exercises such as (2x^4 – 5x^2 + 3x – 7) + (5x^4 + 3x^3 – 7x^2 – 12) and others involving polynomial operations to enhance your understanding of the material.

  1. Today in Algebra 2 • Go over homework • Get calculator. • Notes: Arithmetic with Polynomials • Homework

  2. (2x4 – 5x2 + 3x – 7) + (5x4 + 3x3 – 7x2 – 12)= 7x4 + 3x3 – 12x2 – 19 2) (3x6– 2x4 + 6x3 + 11) – (8x5 – 3x3 + 5x – 7)= 3x6 – 8x5 – 2x4 + 9x3 – 5x + 18

  3. (2x – 9)(4x + 3)= 8x2 + 6x – 36x – 27= 8x2 – 30x - 27 • (5x2 – 7x – 2)(-4x – 3) -20x3 – 15x2 + 28x2 + 21x + 8x + 6= -20x3 + 13x2 + 29x + 6
