Find the solution of the square root of the quantity of x plus 2 plus 4 equals 6, and determine if it is an extraneous solution.

I guess we have

 

√(x + 2)  + 4   =  6          subtract 4 from both sides

 

√(x + 2)  =  2             square  both sides

 

x + 2    =  4              subtract 2 from both sides

 

x  =  2

 

Not extraneous
