Respuesta :

The solution of the equation √x+2 + 4 = 6 is x = 2 and it is not an extraneous solution

How to find the solution of an equation?

The solution of the equation can be found as follows;

√x+2 + 4 = 6

subtract 4 from both sides

√x+2 + 4 - 4 = 6 - 4

√x+2  = 2

square both sides

(√x+2)² = 2²

x + 2 = 4

x= 4 - 2

x = 2

Therefore the solution is x = 2 and it is not a extraneous solution.
