1. 5-Minute Check APK Collect like terms and arrange in descending order.
1) 4x3 + 6x4 – 2x4 + 8x
4x4 + 4x3 + 8x
2) 3x – 5x x0
– 2x + 7
3) Evaluate 4x3 + x2 – 2 for x = 0 and x = 1
When X = 0 Answer -2
When X = 1 Answer 3

2. 5.7 Addition of Polynomials
Objectives:
Students will add polynomials by first collecting like terms.
Why? So you can apply addition rules for polynomials in real world applications.
Mastery is 80% or better on 5-minute checks and indy practice.

3. Skill Develop Example 1 Add (5x2 + 3x + 4) + (3x2 + 5) 3x2 + 5 = 8x2
