is the polynomial of one variable with second-order and
is the polynomial of two variables with third-order
<h3>What is polynomial?</h3>
Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We have polynomials:
and

For 
In this polynomial, the number of variables is one and the maximum power of x is 2, therefore:
This is the polynomial of one variable with second order.
In polynomial,
there are two variables x and y.
The maximum power of x is 3( x has a power of 2 and y has a power of 1)
This is the polynomial of two variables with third order.
Thus,
is the polynomial of one variable with second-order and
is the polynomial of two variables with third-order.

Answer:
Step-by-step explanation:
Given quadratic equation:

The solution of the given quadratic eqn is given by using Sri Dharacharya formula:

The above solution is for the quadratic equation of the form:

From the given eqn
a = 1
b = 3
c = 
Now, using the above values in the formula mentioned above:



Now, Rationalizing the above eqn:


Solving the above eqn:

Solving with the help of caculator:

The precise value upto three decimal places comes out to be:

This is a typical work problem in algebra. The approach to this is using the equation: Rt = 1, where R is the rate per person working, t is the amount of time worked by an individual. All their rates must equal to 1. The solution is as follows:
12/x + 15/x = 1
Solving for x,
x = 27 hours
So, if they work together, they can finish the work in 27 hours.
Its the same time 80 minutes= 1 hour and 20 minutes
