Which of the following expressions are perfect-square trinomials? Check all of the boxes that apply.

x2 – 16x – 64

4x2 +12x + 9

x2 + 20x + 100

x2 + 4x + 16

x² + 1477/2 x + 49

7/2

Now, write x² - 16x + 64 = -8 as (x - 8)² = -16(x - 8)² = -8(x - 16)² = -16(x - 16)² = -8

(x - 8)² = -16

(x - 8)² = -8

(x - 16)² = -16

(x - 16)² = -8
