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 \(b = 11\).

Step2: Apply the formula

Substitute \(a = x\) and \(b = 11\) into the formula:
\((x - 11)^2 = x^2 - 2\times x\times11 + 11^2\)

Step3: Simplify the terms

Calculate each term:
\(-2\times x\times11=-22x\) and \(11^2 = 121\).
So, \((x - 11)^2=x^2-22x + 121\)

Answer:

\(x^2-22x + 121\)
