Answer and step-by-step explanation:

  • Using the FOIL method we can find the square of (x - 6).

  • F stands for the first terms of the binomial.
  • O stands for the outer terms of the binomial.
  • I stands for the inner terms of the binomial.
  • L stands for the last terms of the binomial.

  • We will multiply the binomials following the FOIL method.

  • (x - 6)(x - 6)

  • F: (x)(x) = x^2
  • O: (x)(-6) = -6x
  • I: (-6)(x) = -6x
  • L: (-6)(-6) = 36

  • = x^2 - 6x - 6x + 36
  • = x^2 - 12x + 36

Therefore, the answer is b. x^2 - 12x + 36.
