Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "k2"   was replaced by   "k^2". 

Rearrange:

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

                     4*k^2-7*k^2-(k^2)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  ((4 • (k2)) -  7k2) -  k2  = 0 
 Step  2  :

Equation at the end of step  2  :

  (22k2 -  7k2) -  k2  = 0 

Step  3  :

Equation at the end of step  3  :

  -4k2  = 0 

Step  4  :

Solving a Single Variable Equation :

 4.1      Solve  :    -4k² = 0 

 Multiply both sides of the equation by (-1) :  4k² = 0


Divide both sides of the equation by 4:
                     k² = 0
 
 When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:  
                      k  =  ± √ 0  

 Any root of zero is zero. This equation has one solution which is  k = 0
