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.
