1. Answer:

   [tex]13x {}^{2} – 26x + 13 = 0[/tex]

   [tex]divide \: the \: equation \: by \: 13[/tex]

   [tex]x {}^{2} – 2x + 1 = 0[/tex]

   [tex]x {}^{2} – x – x + 1 = 0[/tex]

   [tex]x(x – 1) – 1(x – 1)[/tex]

   [tex](x – 1)(x – 1) = 0[/tex]

   [tex](x – 1) {}^{2} = 0[/tex]

   [tex]x – 1 = 0[/tex]

   [tex]x = 1[/tex]
