HELP PLS What are the roots of the equation?
x^2(4x - 5) (7x - 13) = 0

i need the steps of how to get the answer

If the answer is wrong delete it

Step-by-step explanation:

STEP  1:

x2 • (4x - 5) • (7x - 13)  = 0  

STEP  2:

 x2 • (4x - 5) • (7x - 13)  = 0  

STEP 3:

Theory - Roots of a product

3.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation:

3.2      Solve  :    x2 = 0  

Solution is  x2 = 0

Solving a Single Variable Equation:

3.3      Solve  :    4x-5 = 0  

Add  5  to both sides of the equation :  

                     4x = 5

Divide both sides of the equation by 4:

                    x = 5/4 = 1.250

Solving a Single Variable Equation:

3.4      Solve  :    7x-13 = 0  

Add  13  to both sides of the equation :  

                     7x = 13

Divide both sides of the equation by 7:

                    x = 13/7 = 1.857

Three solutions were found :

x = 13/7 = 1.857

x = 5/4 = 1.250

x2 = 0

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
