Question

simplify

Answer 1

\[D=\sqrt{(C-A)^{2}+(D-B)}^{2}\]

Answer 2

That last ^2 is supposed to be like the first one, (D-B)^2.

Answer 3

The actual question is to find the distance (distance formula) between (A,B) (C,D)

Answer 4

there's not much that can be done in terms of simplifying

Answer 5

you could expand out (C-A)^2 and (D-B)^2, but that's about it

Answer 6

Right. I think since it is just the distance formula that answer is ok. Thanks.
