\beginsolution Let $[G:H] = 2$, so $H$ has exactly two left cosets: $H$ and $gH$ for any $g \notin H$. Similarly, the right cosets are $H$ and $Hg$. For any $g \notin H$, we have $gH = G \setminus H = Hg$. Thus left and right cosets coincide, so $H \trianglelefteq G$. \endsolution Dummit And Foote Solutions Chapter 4 Overleaf High Quality
