Expansions of Algebraic Expressions The formula: a(b+c) = ab + ac
Algebraic Expansion. (a+b)(c+d)=ac+ad+bc+bd and (a+b)(a-b)= a ² – b² difference of square (a+b)² = a² + 2ab + b² perfect square (a-b) ²=a²-2ab+b²
ExpansionExpansion of two terms with power n, where n∈Z+. Hence Binomial Theorem use. Binomial theorem

The binomial theorems are a result of expansion of powers of binomial term. It also give sums of two terms. The coefficients of the terms in the expansion are the binomial coefficients. Coefficient of terms are calculate through pascal triangle or combination method. The concept is also related with algebra and calculus. binomial theorem p p
