Answer:

Step-by-step explanation:

a.) c = 9

To get a perfect square you must divide the bx or 6x in this situation then square it.

6/2 = 3

3^2 = 9

b.) (x - 1)(x - 5)

x^2 - 6x + 9 = -5 + 9

x^2 - 6x + 9 = 4

x^2 - 6x + 9 - 4 = 4 - 4

x^2 - 6x + 5 = 0

(x - 1)(x - 5)

x - 1 = 0

x = 1

x - 5 = 0

x = 5
