  • (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: The formula is $(a+b)(c+d) = ac+ad+bc+bd$. Learn to apply and simplify expressions like $(2x – 1)(3x + 2)$ and $(-3x +2)(5 – y)$.
  • (2:38) Tips for Binomial Expansion: Carefully identify terms and signs, apply the distributive law step-by-step, and combine like terms for the final simplified expression.
