Answer:
x=-8
Step-by-step explanation:

on squaring both sides

either x-2=0 or x+8=0
either x=2 or x=-8
Putting x=2 in original equation, we get

7=7 hence, it is not an extraneous solution
Putting x=-8 in original equation

i.e. 3=-3
Hence, x=-8 is an extraneous solution (since it doesn't satisfy the original equation)
Answer:

Answer:
3
Step-by-step explanation:
List all possible factors of each number. The GCF will be the largest number they both share
Factors of 18: 1, 2, 3, 6, 18
Factors of 15: 1, 3, 5, 15
The largest number they both share is 3, so that is the GCF
Ummm ... idk and ehhem what is the questions in this anyway
