X² = 5x - 6
x² - 5x  + 6 = 0
(x - 2) (x - 3) = 0

X^2- 5x+6,
= (x + __)(x + __)
to fill out the blanks, find two numbers that adds up to be -5, and has a product of 6, so in this case the two numbers are -2 and -3
-2 x -3 = 6
-2 + -3 = -5
so.
(x + (-3))(x + (-2))
= (x -3)(x-2)

so the answer is b

CHECK:
(x -3)(x-2)
= x^2 - 2x - 3x + 6
= x^2 - 5x + 6
