Answer:


x^2 + 10x + 25

Explanation:

Hello!

Formula:
(a +b)^2 = a^2 + 2ab + b^2

  • a = x
  • b = 5

Plug it into the formula and simplify.

Simplify


  • (a +b)^2 = a^2 + 2ab + b^2

  • (x +5)^2 = x^2 + 2(x)(5) + 5^2

  • (x +5)^2 = x^2 + 10x + 25

The answer is the first option:
x^2 + 10x + 25.
