Binomial Expansion: Understanding (a+b)^6
In algebra, binomial expansion is a fundamental concept that involves expanding expressions of the form (a+b)^n, where n is a positive integer. One such expression is (a+b)^6, which is a crucial concept in mathematics and has numerous applications in various fields. In this article, we will delve into the world of binomial expansion and explore the concept of (a+b)^6.
What is Binomial Expansion?
Binomial expansion is a process of expanding an expression of the form (a+b)^n, where a and b are variables and n is a positive integer. The expansion involves expressing the expression as a sum of terms, each term being a product of a power of a and a power of b.
The Binomial Theorem
The binomial theorem is a mathematical formula that describes the expansion of (a+b)^n. The formula is as follows:
(a+b)^n = a^n + na^(n-1)b + (n(n-1)/2!)a^(n-2)b^2 + ... + b^n
Expanding (a+b)^6
Using the binomial theorem, we can expand (a+b)^6 as follows:
(a+b)^6 = a^6 + 6a^5b + 15a^4b^2 + 20a^3b^3 + 15a^2b^4 + 6ab^5 + b^6
This expansion consists of 7 terms, each term being a product of a power of a and a power of b.
