Answer:
Factoring
Step-by-step explanation:
To solve the equation 
, you must apply the factoring method.
You must find two real numbers b and c such that:
and
Then the expression:
You can prove that:
So
or 
or 
(x+2) - (x-2) = 5. (x-2) (x+2) 6. (x+2)² - (x² - 2)² = 5. (x+2) (x-2) 6. (x² + 4x+4) - (x² - 4x + 4) = 5. x² - 4 6. (x² + 4x + 4 - x² + 4x - 4) = 5. x² - 4 6. 8x = 5.
Wheres the equation? can answer question if there's not problem.
