Answer:
So these two equation can be related by identity
Step-by-step explanation:
We have given equation
And
We know the algebraic identity
From this identity
can be written as (x+1) (x-1)
And using same identity can be written as
So these two equation can be related by identity
Answer:
-6 is an extraneous solution.
Step-by-step explanation:
We can start by solving this problem.
First, to remove the square root, we can square both sides.
Next, we can subtract both sides by (x+10)
Then, we can factor out the equation.
Given this, it seems like -1 and -6 would be correct. Plugging this back into the original equation, though,
-1 + 4 = √(-1 + 10)
3 = 3
-6 + 4 = √(-6+10)
-2 ≠ 2
Therefore, -6 is an extraneous solution.
