Formula: [tex](a +b)^2 = a^2 + 2ab + b^2[/tex]

  • a = x
  • b = 5

Plug it into the formula and simplify.

Simplify

  • [tex](a +b)^2 = a^2 + 2ab + b^2[/tex]
  • [tex](x +5)^2 = x^2 + 2(x)(5) + 5^2[/tex]
  • [tex](x +5)^2 = x^2 + 10x + 25[/tex]

The answer is the first option: [tex]x^2 + 10x + 25[/tex].
