Well the distance formula is √(x₂ - x₁)² + (y₂ - y₁)²
First thing's first, his calculations are wrong.
First instead of doing (x₂ - x₁)² + (y₂ - y₁)²  he did (x₂ - x₁)² - (y₂ - y₁)²  (subtracted instead of added) That means the answer should have came down to √25 + 4 meaning the answer is √29 not √21

Answer:

Well the distance formula definitely is √(x₂ - x₁)² + (y₂ - y₁)² First thing''s first, his calculations kind of are wrong, which for the most part is quite significant. First instead of doing (x₂ - x₁)² + (y₂ - y₁)² he did (x₂ - x₁)² - (y₂ - y₁)² (subtracted instead of added) That kind of means the answer should for the most part have came down to √25 + 4 meaning the answer for the most part is √29 not √2, basically contrary to popular belief.
