Answer
Midpoint $=(2\sqrt{2},0)$
Work Step by Step
$(\sqrt{18},-4)$ and $(\sqrt{2},4)$
The midpoint of a segment with endpoints $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is $\Big(\dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{2}\Big)$
Substitute the given points into the formula and evaluate:
Midpoint $=\Big(\dfrac{\sqrt{18}+\sqrt{2}}{2},\dfrac{-4+4}{2}\Big)=\Big(\dfrac{3\sqrt{2}+\sqrt{2}}{2},\dfrac{0}{2}\Big)=...$
$...=\Big(\dfrac{4\sqrt{2}}{2},0\Big)=(2\sqrt{2},0)$
