question
express ((x + 4)^2) as a trinomial in standard form.
answer attempt 1 out of 2

Explanation:

Step1: Expand the squared binomial

Use the formula $(a+b)^2 = a^2 + 2ab + b^2$, where $a=x$, $b=4$.
$$(x+4)^2 = x^2 + 2(x)(4) + 4^2$$

Step2: Calculate each term

Compute the products and exponents.
$$x^2 + 8x + 16$$

Answer:

$x^2 + 8x + 16$
