Expanding Double Brackets

🎬 Video Tutorial

  • Understanding Binomial Products: A binomial has two terms, such as $(a + b)$ or $(c + d)$. Multiplying two binomials forms a binomial product, $(a+b)(c+d)$.
  • Expanding Double Brackets Example: For $(2x – 1)(3x + 2)$, apply the distributive law: $2x \cdot 3x + 2x \cdot 2 + (-1) \cdot 3x + (-1) \cdot 2$. This simplifies to $6x^2 + 4x – 3x – 2 = 6x^2 + x – 2$.
  • 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.
