Solution:

Here we have two binomial terms

First we take the first term 2x multiply with other terms

6x2 + 6x

Next term 3

9x+ 9

Combine the like terms we get

= 6x2 + 6x+ 9x+ 9

= 6x2+15x+9

Therefore the final answer is 6x2+15x+9

Example: 3

Multiplication of exponential

Solve 2x3y4.3x4.2y3

2*3 x (3+4) .2y(4+3)

Simplify the above expression we get

6x7.2y7

Therefore the final answer is 6x7.2y7

Example: 4

Fraction multiplication

`(3/4)` * `(2/4)`

First we have to multiply the numerator

3*2 = 6

Next multiply the denominator we get

4*4 = 16

= `6/16`

The simplest fraction is `3/8`

Therefore the final answer is `3/8`

Example for Math Multiplication: 5

Find the area of rectangle with base 8 meter and height 6 meter.

2.  The sum of the ages of Daniel and his brother David is 46 years. If the age of the David is 24 years what will be the age of the Daniel?

Solution:

Let the age of Daniel be x years.

The age of his brother David = 24 years.

Sum of both of their ages =(x+ 24) years.

But this sum is given as 46years.

So x + 24 = 46.

x =46 - 24

x =22

Thus the age of the Daniel is 22 years.

Degree of Polynomial Calculator

INTRODUCTION ABOUT DEGREE OF POLYNOMIAL CALCULATOR:       

In arithmetic, a polynomial is an expression of finite length constructed from variables and constants, using only the addition, subtraction, multiplication operations, and non-negative, whole-number exponents. The maximum power of the variable in a polynomial is called the degree of the polynomial. A term with no variables is called a constant term and its degree is zero.I like to share this Polynomial Solver with you all through my article.

Find the Degree of Polynomial:

CONDITION FOR POLYNOMIAL:

In polynomial the variable should not involve in division operation.

Ex: `x^2 -4x+7, x^3 +5x^2-x+6, ` it is a polynomial.

Ex: `x^2 -4/x+3/2,` not a polynomial.

General form for degree of Polynomial Calculator:

A polynomial function is a function that can be defined as,

`f(x)=a_nx^n+a_(n-1)x^(n-1)+...+a_2x^2+a_1x+a_0`

Where n is a non-negative integer and `a_0, a_1,a_2,` ...,` a_n ` is constant coefficients.

First Degree of polynomial calculator:  

The first degree polynomial is the polynomial that has only one variable. The variable may be x, y or z and it is easy to find the value for the variable. The combinations of two first degree polynomials are called as second degree polynomial.

Second degree polynomial calculator:

In this equation 6x2+5x+2  the power of x is 2. so it is a second-degree polynomial or a polynomial of degree 2.

POLYNOMIAL CALCULATOR:

To solve the polynomial in calculator, first we have to enter the two polynomials then click anyone of the button like add, subtract, multiply, division and factor and the equivalent operation will be performed and answer will be displayed. Thus the polynomial calculator is shown below.



Example and Practice Problem for first and Second Degree Polynomial Calculator:

First degree polynomial calculator:

Example 1:

Determine the value for the first degree polynomial 2x+10 = 12.

Solution:

The given first degree polynomial is 2x+10 = 12.

For the above polynomial, subtract 10 on both sides of the equation.

2x +10-10 =12-10

2x = 2

Divide by 2 on both sides of the above equation.

`(2x)/2 = 2/2`

x = 1

The value for the first degree polynomial 2x+10 = 12 is 1.

Second degree polynomial calculator:

Example 1

Find whether the given expression is a second degree polynomial or not.

(x - 1) (x - 2) = 0

Solution:

Multiply two expressions in the left hand side,

(x - 1) (x - 2) = 0

x(x-2) -1(x-2) =0

x2 -2x -x + 1(2) = 0

x2 -3x +2 = 0

So, the highest exponent of variable x is 2.

So, the given polynomial equation is second degree polynomial equation.

Practice Problem for first Degree Polynomial:

1.Find the value for the first degree polynomial of 2x+ 5 = 6.

Answer: The polynomial equation is second degree polynomial equation.

Lower Quartile

Introduction to lower quartile:

In descriptive statistics, a quartile is any of the three values which divide the sorted data set into four equal parts, so that each part represents one fourth of the sampled population. Lower Quartile is one type of quantile.In that quartile, the 25 % of data which lie in the lower half of the data set is called as lower quartile. We can also define it as the middle value of the lower half.

For example,

21, 5, 22, 33, 17, 36, 14, 42, 15, 35, 27


Arrange the data in ascending order,

5, 14, 15, 17, 21, 22, 27, 33, 35, 36, 42

In the above Data set,

15 is lower quartile.

Calculation of Lower Quartile:

Lower Quartile for Odd data set:

Let us see how to calculate the lower quartile of the data set that contains odd numbers.

Step1:  First find the median of the data set. The median divide the data set into upper and lower part.

Step2:  Find the median for lower part of the data set .That median is called as lower quartile.                    

Ex: Data Set: 8, 49, 53, 19, 45, 44, 11, 41, 47, 51, 39

Ordered Data set: 8, 11, 19, 39, 41, 44, 45, 47,49,51,53

Median (Mid value) =44

Lower part = 8, 11, 19, 39, 41

Upper part = 45, 47,49,51,53

Lower quartile (Median of lower part) = 19

Lower Quartile for Even Data set:

Let us see how to calculate the lower quartile of the data set that contains even numbers.

Step 1: Find the Median of the data set by calculating the average of the data set.

Step 2: Next in the lower part, find the median by calculating the average. That value is known as lower quartile.

Ex: Data set: 13, 6, 24, 33, 9, 38, 16, 46, 19, 53, 26, 65

Ordered data set: 6,9,13,16,19,24,26,33,38,46,53,65

Median: (24+26)/2= 25

Lower quartile:  (24+33)/2= 28.5
