Question

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

Explanation:

Step1: Recall the formula for \((a - b)^2\)

\((a - b)^2=a^{2}-2ab + b^{2}\)

Step2: Identify \(a\) and \(b\)

Here \(a = x\) and \(b = 8\)

Step3: Substitute values into the formula

\((x - 8)^2=x^{2}-2\times x\times8+8^{2}=x^{2}-16x + 64\)

Answer:

\(x^{2}-16x + 64\)
