Solution - Radical equations

Radical Equation entered :

     0 = √x-9

Step by step solution :

Step  1  :

Isolate the square root on the left hand side :

     Original equation
     0 = √x-9

     Isolate
     -√x-9 = -0

      Tidy up
     √x-9 = 

Step  2  :

Eliminate the radical on the left hand side :

     Raise both sides to the second power
     (√x-9)² = ()²

     After squaring
     x-9 = 

Step  3  :

Solve the linear equation :

     Rearranged equation
     x -9 = 0

     Add  9  to both sides
     x = 9

     A possible solution is :
     x = 9

Step  4  :

Check that the solution is correct :

     Original equation, root isolated, after tidy up
     √x-9 = 

     Plug in 9 for  x 
      √(9)-9 = 

      Simplify
      √0 = 0
      Solution checks !!
     Solution is:
      x = 9
