question
express ((x + 10)^2) as a trinomial in standard form.

Explanation:

Step1: Expand using square formula

Recall the perfect square formula: $(a+b)^2 = a^2 + 2ab + b^2$. Here, $a=x$, $b=10$.
$$(x+10)^2 = x^2 + 2(x)(10) + 10^2$$

Step2: Calculate each term

Simplify the individual terms:
$$x^2 + 20x + 100$$

Answer:

$x^2 + 20x + 100$
