you need to know about:

  • algebra

let's solve:

  1. [tex] \sf rewrite \: 105 \: as \: 100 + 5 : \\ \sf (100 + 5 {)}^{2} [/tex]
  2. [tex] \sf use \: (a + b {)}^{2} = {a}^{2} + 2ab + {b}^{2} \: to \: simplify : \\ \sf {100}^{2} + 2.100.5 + {5}^{2} [/tex]
  3. [tex] \sf simplify \: squres : \\ \sf 10000 + 2.100.5 + 25[/tex]
  4. [tex] \sf simplify \: multipication : \\ \sf10000 + 1000 + 25[/tex]
