square root of (4x+41)=x+5
4x+41>=0
x >= -10.25
(square root of4x+41)^2=(x+5)^2
4x+41=x^2+10x+25
x^2+6x-16 =0
x +8
x -2
(x+8)(x-2)=0
x= -8
x= 2 extraneous
Answer:
The correct option is 1.
Step-by-step explanation:
The given equation is

Taking square on both the sides.

![[\because (a+b)^2=a^2+2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%2Bb%29%5E2%3Da%5E2%2B2ab%2Bb%5E2%5D)






Check the equation by x=2.



LHS=RHS, therefore x=2 is not an extraneous solution.
Check the equation by x=-8.



LHS≠RHS, therefore x=-8 is an extraneous solution.
Therefore option 1 is correct.
