(0:01)Square of a Binomial Formula: $(a + b)^2 = a^2 + 2ab + b^2$.
(0:38)Geometric Interpretation: Visualising $(a + b)^2$ as the area of a large square, which is the sum of $a^2$, $b^2$, and $2ab$ (small rectangles within the square).
(1:10)Difference of 2 Squares: $(a + b)(a – b) = a^2 – b^2$
(1:28)Step-by-Step Example of Binomial Theorem: Practice with expressions like $(-2x + 3)^2$ and $(5x – 2y)^2$ by identifying $a$ and $b$ terms, applying the appropriate formula, and simplifying to reach the solution.
