Answer:

A. the difference of two squares

Step-by-step explanation:

Please use the symbol " ^ " to indicate exponentiation.

Then we have x^2 - 11^2, which is the difference of two squares:

x^2 is a square, the square of x; and 11^2 is a square, the square of 11.

A. the difference of two squares

Note that a "difference of squares" is easily factored:

a² - b² = (a - b)(a + b)

and so your x² - 11² factors as follows:  (x - 11)(x + 11)
