Question 65602
QUESTION


Solve



square root of c - 16 = 4 - square root of c




ANSWER:



square root of c - 16 = 4 - square root of c



Shift all c terms in one side constants to the other side,



For that  add (square root of c ) to    both sides  of the equation.



==> 
square root of c - 16 + square root of c = 4 - square root of c + squarert c




==> 2 ( square root of c ) -16 = 4



Add 16 on both sides of the equation,




==> 2 ( square root of c ) -16 + 16 = 4 + 16





==> 2 ( square root of c ) = 20




Divide both sides by 2




==>  square root of c =  20/2




==> square root of c = 10




Here we want to solve  for c, so square both sides of the equation,




==> (square root of c )^2= 10^2




==>  c = 100




So the solution is,  c = 100




Hope You understood.
