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

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
