x² - y² +6y -9
= x² -(y²-6y +9)
using (a-b)² = a² -2ab +b²
= x² -(y-3)²
using a²-b² = (a-b)(a+b)
= (x-y+3)(x+y-3)
I hope you understand the approach.
All the best!

Hello there !
______________________________________________________
x² - y² + 6y - 9
x²-(y²-6y+9)
x²-[(y-3)²]
[x+(y-3)] [x-(y-3)]
(x+y-3) ( x-y+3)

x²-[(y-3)²]
[x+(y-3)] [x-(y-3)]
(x+y-3) ( x-y+3)
