Learning Objective
Students will solve by factoring through guided practice and application.
This lesson focuses on solving by factoring. Mathematics provides tools for modeling and analyzing complex systems.
Factoring is writing an expression as a product of simpler expressions. It's the reverse of distributing. For example, 6x + 9 factors to 3(2x + 3) because 3 is common to both terms. Factoring: 1) Find the greatest common factor (GCF). 2) Divide each term by the GCF. 3) Write GCF times what remains. Factoring simplifies expressions and is essential for solving equations. It reveals structure and makes complex problems simpler!
As you engage with this material, consider both the theoretical foundations and practical applications. Think critically about how this concept builds on prior knowledge and where you might apply it beyond the classroom.
Challenge yourself to go beyond memorization—seek to understand the "why" behind the processes and principles.
