Which of the following is equal to (n – 3)2*square* if
n = 11? Choose the correct choice:
A) (n + 6)(n – 6) B) (n + 5)(n – 7) C) (n + 4)(n – 8) D) (n + 3)(n – 9) E) (n + 2)(n – 10)
If n = 11, then:   (n – 3)2 = (11 – 3)2 = 82 = 64   Substitute 11 for n into each answer until you find one that equals 64:   (n + 6)(n – 6) = (17)(5) = 85   (n + 5)(n – 7) = (16)(4) = 64 You’ve found a match   correct answer (n + 5)(n – 7))(n + 5)(n – 7)
