Answer:
(6 + x + y) (6 - x - y)
Step-by-step explanation:
36 - x² - y² - 2xy [given]
=> 36 - [x² + y² + 2xy] [After taking (-1) common]
=> 6² - [x - y]² [6 * 6 = 36 and (a + b)² = a² + b² +2ab]
=> (6 + x + y) (6 - x - y) [a² - b² = (a + b) (a - b)]

Answer:
36-x²-y²-2xy
= 36-{(x)²+2*x*y+(y)²}
= (6)²-(x+y)²
= (6+x+y)(6-x-y)
