Define x:
Let one number be x
The other number is x - 2
Solve x:
x(x - 2) = 1443
x² - 2x - 1443 = 0
(x - 39)( x + 37) = 0
x = 39 or x = -37
Find the numbers:
One numer = x = 39
The other number = x - 2 = 39 - 2 = 37
OR
one number = x = -37
The other number = x - 2 = -37 - 2 = -39
Answer: The numbers are 37 and 39 or -37 and -39

Given:
- Difference between two numbers is 2
- Product is 1443
Assumptions:
Let a and b be two numbers.
Consider x representing the numbers.
Solution:
By condition,
x(x - 2) = 1443
x² - 2x - 1443 = 0
By solving,
We get two factors,
(x - 39)( x + 37) = 0
x = 39 or x = -37
If a = 39,
Then,
b = 37
Proof:
39*37 = 1443
39-37 = 2
Hence, a = 39 and b = 37
If a = -37,
Then,
b = -39
Proof:
-37*-39 = 1443
-37-(-39) = 2
Hence, a = -37 and b = -39
