$(x - 3)^2$
$2x + 9$
save answer

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 \(b = 3\).

Step2: Apply the formula

\[

$$\begin{align*} (x - 3)^2&=x^2-2\times x\times3 + 3^2\\ &=x^2-6x + 9 \end{align*}$$

\]

Answer:

\(x^2 - 6x + 9\)
