Question

ERROR ANALYSIS-Describe and Correct the ERROR in Finding the Distance Between the points (-3,-2) and (7,4)

Answer 1

`Rule = \sqrt{ (x2 - x1)^(2) + (y2- y1)^(2)}`


`( 7 - (-3)) ^(2) + (4 - (-2))^(2)`

`\sqrt{10^(2) + 6^(2)} = √(100 +36) = √(136)`

`√(136) = 2√(34)`

Namely,

Shouldn't be
`( 7 - (-3)) ^(2) - (4 - (-2))^(2)`

Should be ;
`( 7 - (-3)) ^(2) + (4 - (-2))^(2)`

Have a nice day..
