D=sqrt%28%28x%5B2%5D-x%5B1%5D%29%5E2+%2B+%28y%5B2%5D-y%5B1%5D%29+%5E2%29%29
D%5E2=%28x%5B2%5D-x%5B1%5D%29%5E2+%2B+%28y%5B2%5D-y%5B1%5D%29+%5E2%29 Square both sides to remove square root.
Use the additive inverse of %28y%5B2%5D-y%5B1%5D%29%5E2.
D%5E2-%28y%5B2%5D-y%5B1%5D%29+%5E2=%28x%5B2%5D-x%5B1%5D%29%5E2 Simplify.
+/-sqrt%28D%5E2-%28y%5B2%5D-y%5B1%5D%29+%5E2%29=%28x%5B2%5D-x%5B1%5D%29 Take the square root of both sides, could be + or -.
x%5B1%5D+/-sqrt%28D%5E2-%28y%5B2%5D-y%5B1%5D%29+%5E2%29=+x%5B2%5D Use the additive inverse of x%5B1%5D}
x%5B2%5D=x%5B1%5D+/-sqrt%28D%5E2-%28y%5B2%5D-y%5B1%5D%29%5E2%29 Final answer.
