Page 2: Notable Identities
This page focuses on important algebraic identities, specifically the square of a sum and the square of a difference. It provides formulas and examples for these notable identities, which are essential for simplifying and factoring algebraic expressions.
Definition: Notable identities are algebraic formulas that represent specific patterns in mathematical expressions.
Vocabulary: The square of a sum is represented by (a+b)², while the square of a difference is (a-b)².
Example: Using the square of a sum identity, we can expand (x+5)² into x² + 10x + 25.
Highlight: Memorizing these notable identities can significantly speed up algebraic calculations and problem-solving.
