Question

Find the distance between the following pair of points:

( - 2, - 3) and (3, 2)

Answer 1

by simplifying the answer will be 
d=√50

Answer 2

distance between two point = {(X2 - X1)^2 + (Y2 - Y1)^2}^1/2
putting value of X1,X2,Y1,Y2 we get
distance = {(5)^2 + (5)^2}^1/2
             = 50^1/2
