__Binomial Theorem__

The Binomial Theorem is a mathematical concept used to expand expressions like (a + b)^n. It allows for the simplification of such expressions into a sum of terms with specific coefficients. This theorem is essential in algebra and has applications in various fields like probability and combinatorics.

The general form of the Binomial Theorem is given by: (a + b)^n = C(n, 0) * a^n * b^0 + C(n, 1) * a^(n-1) * b^1 + … + C(n, r) * a^(n-r) * b^r + … + C(n, n) * a^0 * b^n

Here, C(n, r) represents the binomial coefficient, also known as “n choose r”, which calculates the number of ways to choose ‘r’ items from a set of ‘n’ items.

### Expansion of Binomial Expressions

The expansion of binomial expressions is a crucial aspect of the Binomial Theorem, allowing for the simplification and expansion of expressions in the form (a + b)^n. This subtopic delves into the systematic process of expanding binomial expressions, revealing the individual terms and coefficients within the expanded form.

#### Key points

**Formula Application**: The Binomial Theorem formula is applied to expand binomial expressions by raising the binomial (a + b) to a given power ‘n’.**Term Calculation**: Each term in the expansion corresponds to a specific power of ‘a’ and ‘b’, with coefficients determined by the binomial coefficients.**Binomial Coefficients**: The binomial coefficients, denoted as C(n, r) or “n choose r”, play a crucial role in determining the coefficients of each term in the expansion.**General Form**: The expanded form of a binomial expression consists of a series of terms, each representing a combination of powers of ‘a’ and ‘b’, multiplied by the corresponding coefficients.**Applications**: Understanding the expansion of binomial expressions is essential for various mathematical applications, including algebraic manipulations, series expansions, and probability calculations.
