Find the solution of the square root of the quantity of x plus 3 plus 4 equals 6 and determine if it is an extraneous solution
answers are:
x = 1; not extraneous

x = 1; extraneous

x = 29; extraneous

x = 29; not extraneous

First we need to write down this equation

now we switch 4 to other side and subtract it from 6


Now we square both sides
x+3 = 4
and we get x = 1

If we replace x=1 in starting equation we get 6=6 which is not extraneus

Answer is first option

3x+9+4x+x=8x+9that's the answer for your question.
