Answer 2

Answer:

your answer

Step-by-step explanation:

Pull out like factors :

  4x - x2  =   -x • (x - 4)  

Equation at the end of step

2

:

 -x • (x - 4)  = 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  :    -x = 0  

Multiply both sides of the equation by (-1) :  x = 0

Solving a Single Variable Equation:

3.3      Solve  :    x-4 = 0  

Add  4  to both sides of the equation :  

                     x = 4

Two solutions were found :

x = 4

x = 0
