## Important Topics Covered under Higher Algebra by Hall and Knight Chapter 14: Binomial Theorem, Any Index

Introduction

In this chapter, you will get to learn the formulae when the values of the index is a negative value or a fractional value. The principle of permanence of the equivalent forms is followed here, which means that in any algebraical product, the order of the product will remain the same even if the quantities involved are whole numbers, fractions, positive, or negative integers.

Binomial Theorem when the Index is a Positive Fraction

We assume the functions and

It can be proved using the permanence of equivalent forms principle that

f(m) x f(n) x f(p)… to k factors=f(m+n+p+… upto k terms)

Therefore, proving that the binomial theorem holds true for positive fractional index.

Binomial Theorem when an Index is a Negative Number

We already know that f(m)f(n)=f(m+n). Now, if we replace m by -n where n is a positive quantity, we get f(-n)f(n)=f(-n+n)=f(0)=1

Therefore, (1-x)-n=1+(-n)x+(-n)(-n-1)x2/1.2+… proving that the binomial theorem holds true for any given negative index.

The convergent and the divergent series are also discussed in this chapter along with their true arithmetic equivalent.

Formula to Evaluate the General Term

Note that the term nCr is no longer used in the general formula, instead, the formula is written in full where n represents a negative or a fractional number. To find the general term, we use the following formula,

Simplest Term in the Expansion of (1-x)-n

When we expand (1-x)-n, all the terms are positive. The simplest term is given by the following expression

### Exercise Discussion of Hall and Knight Higher Algebra Solutions Chapter 14: Binomial Theorem, Any Index

1. In exercise 14.a, you will be needed to expand given binomial expressions with fractional or negative values as index up to 4 terms. You will also get to find general terms in various equations given in this exercise.
2. There are 37 questions in 14.b in which you will be required to find the simplest or the (r+1)th term. You will get many questions based on the applications of the binomial theorem such as some particular cases of (1-x)nand (1-x)-n.
3. In 14.c, the topics that are covered are the evaluation of the number of homogeneous products of ‘r’ dimensions, terms in the expansion of a multinomial, number of combinations of ‘n’ things taken ‘r’ at a time.
