Algebra and Graphs Expanding Double Brackets

🎬 Video Tutorial

(0:15) Understanding Binomial Products: A binomial has two terms, such as $(a + b)$ or $(c + d)$. Multiplying two binomials forms a binomial product, $(a+b)(c+d)$.
(1:32) Expanding Double Brackets Example: Apply the distributive law to expand $(2x – 1)(3x + 2)$ and $(-3x +2)(5 – y)$, and simplify expressions efficiently.
(2:38) Tips for Binomial Expansion: Carefully identify terms and signs, apply the distributive law step-by-step, and combine like terms if possible for the final simplified expression.
