Question

Math Simplify: (x-11)^2

Answer 1

We are given the following expression

`(x-11)^2`

Let us simplify the above expression.

Recall the formula of perfect square trinomials given by

`(a-b)^2=a^2-2ab+b^2`

Let us apply the above formula to the given expression.

a = x

b = 11

`\begin{gathered} (x-11)^2=x^2-2(x)(11)+11^2 \\ (x-11)^2=x^2-22x+121 \end{gathered}`

Therefore, the simplified expression is

`x^2-22x+121`
