## What is expansion of Binomial theorem?

In the expansion, the first term is raised to the power of the binomial and in each subsequent terms the power of a reduces by one with simultaneous increase in the power of b by one, till power of b becomes equal to the power of binomial, i.e., the power of a is n in the first term, (n – 1) in the second term and so …

## What is Binomial theorem explain it in detail?

binomial theorem, statement that for any positive integer n, the nth power of the sum of two numbers a and b may be expressed as the sum of n + 1 terms of the form. Fast Facts. Related Content. binomial theorem.

What is binomial expansion used for?

Binomial Expansions and Series The binomial formula in statistics is mostly used for counting and for calculating probabilities in experiments. A very similar technique, called binomial series expansion, is used in calculus for rewriting complicated functions into a simpler (binomial) form.

What is binomial theorem class 11th?

The binomial theorem is defined as the process of algebraically expanding the power of sums of two or more binomials. Coefficients of binomial terms in the process of expansion are referred to as binomial coefficients. It is a segment of basic algebra that students are required to study in Class 11.

### What is the expansion formula?

The binomial expansion formulas are used to find the expansion when a binomial is raised to a number. The binomial expansion formulas are: (x + y)n = nC0 0 xn y0 + nC1 1 xn – 1 y1 + nC2 2 xn-2 y2 + nC3.

### What is binomial theorem example?

A binomial is an algebraic expression with two terms. For example, a + b, x – y, etc are binomials. We have a set of algebraic identities to find the expansion when a binomial is raised to exponents 2 and 3. For example, (a + b)2 = a2 + 2ab + b2.

What is binomial theorem and why is it used?

The Binomial theorem tells us how to expand expressions of the form (a+b)ⁿ, for example, (x+y)⁷. The larger the power is, the harder it is to expand expressions like this directly.

Why is binomial theorem important?

The binomial theorem gives us the general formula for the expansion of (a+b)n for any positive integer n. It also enables us to determine the coefficient of any particular term of an expansion of (a+b)n.

## What is binomial theorem examples?

The Binomial Theorem is the method of expanding an expression that has been raised to any finite power. A binomial Theorem is a powerful tool of expansion, which has application in Algebra, probability, etc. Binomial Expression: A binomial expression is an algebraic expression that contains two dissimilar terms.

## Which chapter is binomial expansion?

What chapter is binomial theorem?

In this segment of Ch 8 Maths Class 11, students are introduced to the basic concept of the Binomial Theorem.
