question
express ((x + 8)^2) as a trinomial in standard form.

Explanation:

Step1: Recall the formula for squaring a binomial

The formula for \((a + b)^2\) is \(a^2 + 2ab + b^2\). Here, \(a = x\) and \(b = 8\).

Step2: Apply the formula

Substitute \(a = x\) and \(b = 8\) into the formula:
\((x + 8)^2 = x^2 + 2\times x\times 8 + 8^2\)

Step3: Simplify the terms

Calculate each term: \(2\times x\times 8 = 16x\) and \(8^2 = 64\). So we get \(x^2 + 16x + 64\).

Answer:

\(x^2 + 16x + 64\)
