Basic Number Theory

Introduction to basic Number theory:

Let us see about the topic is basic number theory is said to be as the complete theory of numbers in which we can study about basic process of math like addition, subtraction, multiplication and division in step by step method. The basic number theory is the basic theory of mathematics. We shall prepare some example of explain basic number theory in the below articles.

Types of Number Theory:

Theron are four types of basic number theory are mostly used in the basic number theory; these types are classified according to the symbol of the number. It will be shown as below,

Addition Number Theory
Subtraction  Number Theory
Multiplying  Number Theory
Division Number Theory

Explanation with Basic Number Theory

Addition Number Theory:

Numbers are used for including process in daily life. The math symbol for addition is plus or +. The math symbol of plus operation is used for adding two or more quantities into single sum of quantities. The two numbers are added jointly to obtain the solution for the sum of two numbers.

For example:

203 + 15 = 218, here, 203 and 15 are addends and 218 are called as sum.

Subtraction Number Theory:

Subtraction number theory get leave in such situations where present is a loss or reduction of somewhat as a result of subtracting a number from several extra number. Subtraction is getting gone part from a total.

For example:

119 – 9 = 110, here, 119 and 9 are minus are called as subtraction.

Multiplying Number Theory:

Here we are leaving to see the basic number theory using multiplication, usually multiplication is called as the constant addition, understand if we are combine the similar 7 groups with 7 objects in each group means it will be written in multiplication format of 7*7=49, we get the same answer in addition also, it will be shown below 7+7+7+7+7 = 49. 

For example:

12 * 7 = 84

Division Number Theory:

In arithmetic divisor is distinct as “the numeral that you are available to divide by”. Divisor of an exacting numeral is also known as the divisor of a given digit.

Dividend /Divisor = Quotient.

For example:

The given number is 60/10

Answer is 6

Solving Polynomial Equations in Factored Form

Introduction to polynomial equations in factored form:
In mathematics, a polynomial is an expression of finite length constructed from variables (also known as indeterminates) and constants, using only the operations of addition, subtraction, multiplication, and non-negative, whole-number exponents. (Source: Wikipedia)

Generally polynomial equations can be written as, x^2 - 3x + 9. Polynomial equations in factored form can be written as

(x - 2) (x - 3).

Example Problems for Solving Polynomial Equations in Factored Form
Solving polynomial equations in factored form example problem 1:

Write the given polynomial expression x^2 - 17x + 16 in factored form.

Solution:

Given polynomial expression is x^2 - 17x + 16

First factorize the given expression, we get

(x^2 - 17x + 16) = (x^2 - 16x - x + 16)

Grouping the first two terms and second two terms, we get

= (x^2 - 16x) - (x - 16)

= x (x - 16) - 1 (x - 16)

= (x - 16) (x - 1)


The factors of the given polynomial expression is (x - 16) and (x - 1)

Answer:

The final answer is (x - 16) and (x - 1)

Solving polynomial equations in factored form example problem 2:

Write the given polynomial expression x^2 + 27x + 140 in factored form.

Solution:

Given polynomial expression is x^2 + 27x + 140

First factorize the given expression, we get

(x^2 + 27x + 140) = (x^2 + 20x + 7x + 140)

Grouping the first two terms and second two terms, we get

= (x^2 + 20x) + (7x + 140)

= x (x + 20) + 7 (x + 20)

= (x + 20) (x + 7)


The factors of the given polynomial expression is (x + 20) and (x + 7)

Answer:

The final answer is (x + 20) and (x + 7)

Solving polynomial equations in factored form example problem 3:

Write the given polynomial expression x^2 + 17x - 434 in factored form.

Solution:

Given polynomial expression is x^2 + 17x - 434

First factorize the given expression, we get

(x^2 + 17x - 434) = (x^2 + 31x - 14x - 434)

Grouping the first two terms and second two terms, we get

= (x^2 + 31x) - (14x + 434)

= x (x + 31) - 14 (x + 31)

= (x + 31) (x - 14)


The factors of the given polynomial expression is (x + 31) and (x - 14)

Answer:

The final answer is (x + 31) and (x - 14)

Introduction:

Polynomial fractions are declaring the rational expression, usual fractions you can do with rational expressions. When dealing with rational expression, you will frequently need to estimate the appearance, and it can be useful to know which values would cause division by zero, so you can pass up these x-values. Ratio of two polynomials is declaring the rational expression.

Definition:

A rational number is a few number that can be printed in the form a/b, there are a is specified the integer and b is also specified the integers and b ? 0. It is needed to declare exclude 0 because the fraction specified the fraction and division by zero is undefined.

Rules

Each problem by factoring everything you can.
Retain information that, even with all the difficult looking functions, a rational expression is just a fraction: you control them using all the rules of fractions that you are common with.
Two rational expressions same to both other. It is known as the rational equation. Rational expression goal is specified the solve for x, it is locate the x value that create the equation is true.

Simplifying Rational Expressions
Simplifying rational expressions becomes easy with little help. Following is a detail explanation of rational expression examples. A rational expression is more than a fraction in which the numerator and/or the denominator are polynomials.

x/52

The x is specified the numerator and 52 is specified the denominator
The 52 is specified denominator, it is a constant, the expression is known as for all real number values of x.

102/x

The 102 is called the numerator and x is called the denominator
Denominator is represents the x is a variable, expression is approximate specified x=0

Basic Method

`(a)/(b)=``(ad)/(bd)`

Additional method

`(a)/(b)+(c)/(b)=(a+c)/(b)`

subtraction method

`(a)/(b)-(c)/(b)=(a-c)/(b)`

Multiplication method

`(a)/(b).(c)/(d)=(ac)/(bd)`

Division method

`(a)/(b)-:(c)/(b)=(ad)/(bc)`

Example

1.  `(10)/(30)`+ `(5)/(20)`

= `(20+15)/(60)`

=  `(35)/(60)`

=   `(7)/(12)`

2.     `(60x^(3))/(80x^(2))`   =   `(10x^(2).6x)/(10x^(2).8)`

=    `(10x^(2).6x)/(10x^(2).8)`

=     `(6x)/(8)`

=   `(3x)/(4)`

3.     `(40)/(60)`       = `(4.10)/(6.10)`         

=  `(4)/(6)`

4.  `(x-5)^(2)`

`x^(2)+25-10x-` `x^(2)+11x`

x+25

5.   `(8)/(6)` -`(5)/(8)`

=   `(32-15)/(24)`

=`(17)/(24)`

6.  `x^(2)+8x = -16`

`x^(2)+16+8x =0`   

`(x+4)^(2)=0`

`x=-4`

Practice problem:

1.`(8x+16)/(4y)` =      `(2x+4)/(y)`

2.  `(4x+2)/(4)`    =   x +  `(1)/(2)`
