Solution - Linear equations with one unknown

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "c2"   was replaced by   "c^2". 

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                     c^2-(5*c)=0 

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

 2.1     Pull out like factors :

   c² - 5c  =   c • (c - 5) 

Equation at the end of step  2  :

  c • (c - 5)  = 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  :    c = 0 

  Solution is  c = 0

Solving a Single Variable Equation :

 3.3      Solve  :    c-5 = 0 

 Add  5  to both sides of the equation : 
                      c = 5

Two solutions were found :

1.  c = 5
2.  c = 0
